The HK SP7 is real and closer than you think. Here's everything actually confirmed, not speculation
Posted by Minute-Log-7098@reddit | Firearms | View on Reddit | 93 comments
For 20+ years the gun community has been asking HK for a civilian MP7. It's actually happening this time.
There's a lot of noise out there so here's what's confirmed vs what's still unknown.
The SP7 is a semi auto only pistol version of the MP7 personal defense weapon. Same gas operated rotating bolt, same 4.6x30mm cartridge, no fun switch. HK also has a carbine version called the PCC7 with a longer barrel and fixed stock.
HK filed a trademark for "SP7" with the EU Intellectual Property Office on February 16, 2024.
In February 2025, TFBTV's James Reeves sat down with HK USA CEO Mike Holley. Holley said on camera there's an "8 out of 10 probability" the SP7 and C36 (civilian G36) reach the US market. He also said not to expect either in 2025.
In September 2025, Germany's Federal Ministry confirmed the SP7 is not classified as a war weapon, removing a major export barrier.
On March 13, 2026, Germany's Federal Criminal Police (BKA) published an official determination classifying the SP7 as a civilian pistol.
They tested the SP7 prototype against a full auto MP7 from their own reference collection and confirmed "only semi automatic firing was possible" and the weapon "cannot be converted" to full auto. That's the final German regulatory hurdle cleared for export.
Spec sheet:
SP7 (pistol): 4.6x30mm, gas operated rotating bolt, 7.09 inch barrel, 15.75 inches overall, no stock, 10 round magazine.
PCC7 (carbine): same caliber and action, 9.45 inch barrel, 27.5 inches overall, fixed shoulder stock, 10 round magazine.
What hasn’t been confirmed…yet:
US pricing. Arms Unlimited has a listing at $2,500 but that's a placeholder. No US retailer has these in hand. For context the SP5 (civilian MP5 in 9mm) runs $3,000 to $3,500 street. If the SP7 actually lands at $2,500 that would be notably cheaper than the SP5.
Release date. Community estimate is Q4 2026 or early 2027. Holley said HK won't announce until they're close to shipping.
Magazine capacity for US market. The German docs show 10 round mags but that may be the Euro spec. The military MP7 uses 20 and 40 round magazines. Whether HK ships US versions with higher capacity mags is unknown.
ATF import approval is still required even with the German export clearance.
Ammo stuff:
4.6x30mm is running about $0.75 to $0.90 per round right now and has been trending down slightly.
Availability is limited since it's primarily been a military cartridge. FN had the same problem with 5.7x28mm when the PS90 launched and it took years for civilian ammo production to catch up.
Expect a similar curve here. If the SP7 sells well and creates real civilian demand, manufacturers will scale up.
The history for anyone unfamiliar:
The MP7 was developed in the late 1990s to meet a NATO requirement for a personal defense weapon that could defeat body armor at close range.
The 4.6x30mm round can penetrate NATO CRISAT armor (20 layers of Kevlar + 1.6mm titanium) at 200 meters. It's been adopted by German KSK, UK SAS, and US DEVGRU.
Red Squadron reportedly carried suppressed MP7A1s alongside HK416s on the bin Laden raid.
A loaded 4.6x30mm round weighs roughly half what a 9mm does, so operators carry significantly more ammo for the same weight. A 40 round MP7 magazine is about the same size as a 30 round MP5 magazine.
My read on this:
Don't put money down on a pre order from anyone who doesn't have them in hand.
Set in stock alerts at EuroOptic and Brownells, watch the HKPRO forums, and wait for HK USA to officially announce. The German regulatory hurdles are cleared. Now it's down to HK USA's timeline and ATF import approval.
If this lands at $2,500 it'll be one of the most interesting releases in years. The real question is whether 4.6x30mm ammo becomes accessible enough to make this a gun you actually shoot rather than a safe queen.
Anyone else tracking this? What do you think realistic US pricing looks like once these actually hit shelves?
bluebeast1562@reddit
4.6mm? How difficult will it be to find that round?
Minute-Log-7098@reddit (OP)
It's niche right now. Running about 75 to 90 cents a round and availability is limited since it's been a military only cartridge.
For context, that's slightly cheaper than 5.7x28mm but way harder to find. FN had the same problem when they launched the PS90, 5.7 was expensive and hard to source for years until civilian demand pushed manufacturers to scale up. If the SP7 sells well expect the same curve with 4.6x30mm.
Until then you're ordering online and planning range trips around ammo shipments, not walking into your local shop and grabbing a box off the shelf.
WVGunsNGoats@reddit
There are four companies making 4.6 ammo, and it can be had as cheap as 30ish dollars a box on ammoseek for 50.
LivingQuail803@reddit
Right all these people whining it’s so niche it’s so expensive it’s available online like everything else
BeeAZL@reddit
I'm sure once the gun gets released, the ammo will actually be in demand and get cheaper as ammo production ramps up
Sub7viaLimeWire@reddit
Maybe this will take up some sp5 sales so I can finally get one. instead of just watching the price rise over the years.
juggarjew@reddit
no lol the SP7 will sell to HK autist who already own multiple SP5s.
The market for the SP5 and SP7 is pretty different due to the 4.6mm round being much, much more expensive than 9mm. Also 9mm can easily be subsonic , this cant. Its a very specific type of PDW weapon that im sure HK autist will fight each other over, but I dont think its going to be nearly as popular as the SP5.
LivingQuail803@reddit
Austist here can confirm
Minute-Log-7098@reddit (OP)
Ha, you and half the HK community. SP5 supply has been brutal the last year. If the SP7 pulls even some of the “I just want an HK PDW” crowd away from the SP5, prices might actually stabilize. Or HK does what HK does and makes 12 of them per quarter and both are impossible to find."
Trogmank80@reddit
If that is the actual price holy fuck. I would have guessed a lot higher
TGGhvacr@reddit
Same I was expecting like at least 4500
bikumz@reddit
This thing gonna end up being 4200 and an extra 500 if you wanna buy the stock.
MTUTMB555@reddit
Stock is like $200 and readily available
bikumz@reddit
I don’t think you get the joke and that’s ok
MTUTMB555@reddit
I get what you’re trying to say, but it doesn’t work when you can already get the stock lol
bikumz@reddit
You can already get a MP7 with a SOT for 40k.
What’s your point again?
LivingQuail803@reddit
Damn 40k is way cheaper than I thought it would be
MTUTMB555@reddit
But we’re talking about the SP7. What is your point? Lmao.
bikumz@reddit
You’re pricing a MP7 stock tho?
MTUTMB555@reddit
I guess just tell funnier jokes, man. I was trying to help you lol
bikumz@reddit
What’s the price of a SP7 stock? “Help me” then.
MTUTMB555@reddit
It’s the MP7 stock. See above.
bikumz@reddit
So we are talking about the SP7. What’s the SP7 stock price?
MTUTMB555@reddit
Idk what “gotcha” you think you’re doing here, but you seem slow. Your joke wasn’t funny. The stock is $200, not $500. It will use the same stock as the MP7, just like the SP5 and SP5K use the same stocks as the MP5 and MP5K, respectively.
Now rub those two little neurons together and I know you’ll get it. Give it time.
bikumz@reddit
The SP7 is pictured to have a 1913 rial on the back. The MP7 stock uses rails built in to receiver. That’s a real gotcha comment. So where SP7 stock that attaches to pic?
Diligent-Parfait-236@reddit
As overpriced as HK is these are absurdly cheap to make in comparison to anything else. At $1000 they'd probably have higher profit margins than 416/7s and mp5s.
bikumz@reddit
They just released a sub-compact handgun on the US market for 1000+. Doubt these would be the same price.
Minute-Log-7098@reddit (OP)
Not the official price. What would you pay for it?
Trogmank80@reddit
People were buying the tp7 for around $4k. I think 2500 - 3000 is reasonable. 2500 is awsome though.
wlogan0402@reddit
With the power of 3d2a someone will make a near 1:1 and make it super safe for under $500
Mountain_Man_88@reddit
Make it .22 mag or .17 hmr too.
NotAurelStein@reddit
CP33 (22lr) with a mp7 kit can be had for around $700 total.
ExpeditedSwine@reddit
I have one. Fun fun
AhrimTheBelighted@reddit
There's a chassis that uses some 5.7 stuff in a MP7 style, thats as close as I am getting without having weird ammo lol.
ClandestinePleb@reddit
Working on it, hit a few bumps
Minute-Log-7098@reddit (OP)
This would be very interesting
Relevant_Baker_2277@reddit
Hk sp7
Prbblystolenhellcat@reddit
Stupid question but theres pretty much no reason regular mp7 mags wouldnt work right? Because i may theoretically have a few 40 rounders ready
Yeet0rBeYote@reddit
It’s crazy that a civilian MP7 is the same price as a TP9
Minute-Log-7098@reddit (OP)
Crazy sauce indeed! The TP9 has been the only game in town for a civilian PDW for years and it's running $2,100 to $2,300.
If (big IF) the SP7 actually lands at $2,500 you're paying roughly the same money but getting 4.6x30mm armor piercing capability vs 9mm, a gas operated action vs roller delayed, and the MP7 pedigree.
The trade off is ammo cost. 9mm is 20 cents a round, 4.6x30mm is 75 to 90 cents. So the TP9 is way cheaper to feed. Depends on whether you want to actually shoot it regularly or you're buying the platform.
Yeet0rBeYote@reddit
Hopefully bringing the MP7 to the civilian market creates a higher demand for 4.6, which may force more companies into the market. We saw this with 5.7, and now there are multiple platforms, even AR-based ones, that use 5.7. Maybe within 10 years we will see more use of commercial 4.6 firearms.
Minute-Log-7098@reddit (OP)
That's exactly what happened with 5.7. When the PS90 and Five-seveN were the only two civilian guns shooting it, ammo was expensive and hard to find. Now you've got the Ruger 57, CMMG Banshee in 5.7, PSA Rock 5.7, and even AR uppers chambered for it. Prices dropped and availability opened up because manufacturers saw the demand. If the SP7 sells well there's no reason 4.6 doesn't follow the same path. Whether it takes 5 years or 10 depends on whether other manufacturers build platforms around it or if HK stays the only game in town.
WVGunsNGoats@reddit
When it was just the Five-Seven and the P90 that shot 5.7x28 it was 17.00 a box of 50 rounds for FN blue tip ammo.
bp_968@reddit
Well sure, and I was paying 110$/1000 for green tip 5.56 too. And around the same time you could buy 5.45x39 for 90-100$ per 1200 rnd case or so.
Inflation and surplus drying up are real things sadly.
WVGunsNGoats@reddit
True but his statement was: “When the PS90 and Five-seveN were the only two civilian guns shooting it, ammo was expensive and hard to find.”
Which is why i posted about how much it actually cost per 50 rounds at that time.
bp_968@reddit
Sure but again, that was 320$ per 1000. Since 556 was 100-150$ per thousand at the time that was expensive. Now 556 is 450$ per thousand and 5.7 is 400-500$ per thousand, making it the same or cheaper then 556.
So yes, 5.7 was more expensive back then, and less available. Since surplus doesn't really exist anymore I won't be surprised to see 4.6 fall to 50-60c a shot but I don't see it hitting 5.7 prices unless a number of other less expensive guns pickup the round.
WVGunsNGoats@reddit
Right now i believe you can get 4.6 for 58 cents or so per round. Maybe with the mp7 coming out we will see the companies who make it ramp up production, otherwise i think buying it now before it drops might be a good idea.
bp_968@reddit
Someone already makes a 4.6 AR based gun. Im too lazy to look it up but its out there somewhere.
Turbulent-Fun-6900@reddit
They need to make it in 9mm, or 5.7 if they have to keep it weird. Hell 22 mag would be legit as well
craeger@reddit
Would one be able to attach the telescoping stock to the sp7 and remove the picatinny?
Minute-Log-7098@reddit (OP)
Short version, no on the rail and yes, but expensive on the stock.
craeger@reddit
What do you mean
Minute-Log-7098@reddit (OP)
The top Picatinny on the SP7 isn't a bolt-on like the military MP7A1 has. HK built the SP7 with a full length integral rail molded into the polymer unibody receiver, and the side slots moved to M-LOK per the BKA and EnforceTac press photos. There's no upper to swap and no screws holding the top rail on, so removing it means taking a dremel to the receiver and you're done with that gun. If you want a cleaner top, your only real move is running a low profile optic and pretending the rail isn't there.
On the stock, the SP7 is imported as a pistol with a 7.09 inch barrel because that's the only path that clears 925(d)(3). The second you attach an MP7 telescoping stock and shoulder it, it's a short barreled rifle under the NFA. Legal route is ATF eForm 1 (5320.1), wait for approval before the stock goes on, and your state has to allow SBRs. Good news is the One Big Beautiful Bill zeroed out the SBR tax stamp effective January 1 of this year, so it's a free stamp now instead of 200 bucks, and eForm 1 approvals have been averaging around two weeks, individual filers sometimes getting through in under ten days. The felony-if-you-jump-the-gun part hasn't changed, stock goes on after the approval email lands, not before. Also worth knowing, once you SBR it you can't unring that bell, it's a rifle forever in ATF's eyes.
If you want a stocked 4.6x30 without the Form 1 dance at all, HK's own PCC7 is the carbine variant with a 9.45 inch barrel and a fixed stock styled off the MP7 telescoping shape, and Tommy Built Tactical's MP7 clone is already shipping and can be bought as either a pistol or a factory SBR.
Caveat on all of this, SP7 still isn't in the US. BKA ruled it semi-auto only back in September and the determination hit the Bundesanzeiger on March 13. ATF import approval is still outstanding. HK USA's CEO Michael Holley publicly put it at eight out of ten odds, some US dealers are already listing Q4 2026 as anticipated availability, skeptics are saying end of 2027.
craeger@reddit
Thanks, but I’m specifically referring to the picatinny in the rear, will I be able to remove that and put the telescoping stock on the sp7, or will H&K make it impossible
Minute-Log-7098@reddit (OP)
Gotcha, so that rear pic stub is real, you can see it in the BKA photos and the EnforceTac shots, and HK absolutely intends for you to use it. The harder question is what's underneath it, and the honest answer is nobody outside HK knows yet because the gun isn't on a shelf to disassemble.
What we do know is HK's playbook from the SP5. On the SP5 the rear isn't fully redesigned, what they actually do is weld a steel block (the sling loop plate, sometimes called the "anti-full" block) that obstructs the MP5 stock's locking lug from seating. The lug recess in the receiver tube is still there, just blocked. SP5 owners regularly run real MP5 stocks two ways.
One, after Form 1 approval, grind the welded block flush and the OEM stock seats normally.
Two, no NFA, run a B&T or SB Tactical adapter that mounts via the receiver push pins and bypasses the lug entirely. So the SP5 precedent is actually "made hard, not made impossible."
For the SP7 specifically, the HKPRO read of the BKA images is that the rear pic stub is "a significant departure from the traditional MP7 folding stock mechanism," which leans toward HK structurally redesigning the rear rather than just blocking it like SP5. But that's an inference from exterior photos, not a teardown. We won't know whether the MP7 stock interface is blocked-but-recoverable or actually gone until somebody pulls one apart.
Practical paths/options for you to consider.
One, easiest and almost certainly viable: Form 1 SBR it (eForm 1, free stamp now, two-ish week average), then run a picatinny-mount telescoping stock off that rear stub. A3 Industries MTS, Haga Defense Universal Telescoping Stock, SB Tactical HKPDW (the HK-specific push-pin model), or a B&T telescoping stock are the realistic options. Looks similar to the military gun in profile, isn't the OEM piece.
Two: if HK followed SP5 architecture and the MP7 lug pocket is still in the receiver under the pic stub. Form 1 first, then aftermarket grinds the obstruction, then you bolt on a real MP7 telescoping stock. This path may or may not exist on the SP7, depends on what's under that pic.
Three: if HK structurally redesigned the rear and the lug pocket is gone. Real MP7 stock requires a custom adapter that doesn't exist yet, and the side loads on a pic stub that wasn't engineered to take a real stock are going to be a question.
Four: skip the whole dance. PCC7 is HK's own carbine variant with a fixed stock styled off the MP7 telescoping in extended position, 9.45 inch barrel, 27.5 inch overall, no Form 1 needed, looks closer to the military silhouette than anything you're bolting onto an SP7 short of a custom adapter.
So the actual answer to your question, you'll be able to remove the rear pic in the sense it's a discrete component, but whether the OEM MP7 stock goes on after that depends on which version of HK's import-compliance architecture they used, and we won't know until tear-down photos exist. HK didn't make this geometry by accident, the rear is the entire reason 925(d)(3) lets the gun in as a pistol.
craeger@reddit
Thanks, I assume most people who want the mp7a1 clone will opt for this.
Minute-Log-7098@reddit (OP)
My pleasure 😊, assumptions are dangerous sometimes.
SentinelZero@reddit
Why this is in 4.6x30 instead of a more readily available cartridge baffles me but is typical HK; nothing in the US market, NOTHING uses 4.6x30mm so this basically mandates its own ammo ecosystem unlike 5.7x28 which has a market and a stable of guns that may use it.
rationis@reddit
Wish they'd make it in 5.7. 4.6 is worse in every way and significantly more pricey to shoot.
SentinelZero@reddit
What even uses 4.6 other than the SP7? The 4.6 was basically DOA in the US market unlike the 5.7 which has a bunch of non-FN guns that chamber it.
Dodo224@reddit
Why worse?
TacTurtle@reddit
Stupid cartridge, fired by only a single firearm.
Dodo224@reddit
Expensive and hard to get, but anything else?
rationis@reddit
Yea, NATO found 5.7 to be 27% more effective on soft tisues and more effective at range. At range the 4.6mm would not consistently tumble after impact while also being the smaller rd. I'd also bet that 4.6 takes a more significant velocity hit from pistol length barrels than 5.7 on account of having to burn more powder. Since 5.7 can match 7.1" MP7 velocities out of a 5" barrel, I'd consider that another adcantage for 5.7.
Don't get me wrong, I'd love an MP7 and very well might pick one up, but if I'm going to choose a round for self defence, its going to be a 5.7 over the 4.6. The best of both worlds with be a 5.7mm MP7 imo.
A_Queer_Owl@reddit
yeah, that's also why the two guns were in limbo for decades. NATO was like "bro, your gun is inadequate" and HK ran to Germany all like "daddy, daddy they're being mean to me!" and then Germany used its position in NATO to tie things up for 30 years until NATO was just like "fine, we'll use both."
earle27@reddit
I’m actually working on some projects that basically amount to a 5.7 MP7. As long as our development schedule stays on track we should have some cool news this summer. We just got past a big milestone in prototyping.
MM_Spartan@reddit
Ammoseek shows it for like 0.68/rd.
Not saying that’s “cheap” territory by any means, but it’s not that bad.
rationis@reddit
Not shipped. $0.69.1 shipped for 4.6 vs $0.40 for 5.7 and people already raise hell over 5.7 prices lol
bikumz@reddit
People raise hell over 5.7 prices because they don’t actually know 5.7 prices
Minute-Log-7098@reddit (OP)
Sometimes dreams come true. But not for you lol.
Minute-Log-7098@reddit (OP)
And I agree on the ammo. If demand comes in (which it looks like it already is from what I’ve seen) then this can get strange

It’s funny, I’ve seen mp7 mags and 4.6 ammo at my local PSA most times I’ve been in there. Always thought it was ironic they had both but we couldn’t get a firearm.
Minute-Log-7098@reddit (OP)
That's the most HK thing I've ever heard. PSA does actually carry 4.6 online so that part tracks. The fact that major retailers are already stocking the ammo before there's even a civilian gun to shoot it with is a good sign for availability if the SP7 does make it stateside.
cthompson07@reddit
It was way before the rumors of the civilian sp7. This picture I took of the mag is dated September 2024 lol.

CMMG makes a Banshee in 4.6
juggarjew@reddit
Everyone needs to understand that the "AP" nature of this weaker than 5.7mm round relies entirely on having a hardened steel penetrator.
As non military/LEO Customer we are not getting any of that ammo, we are getting just standard FMJ and hollow point.
With how expensive the ammo normally costs for 4.6mm and how a large part of its capability has been removed, its kind of a shit round at that point.

This itch has been scratched by my PS90s.

Minute-Log-7098@reddit (OP)
Ha, then it's just a short five-seven.
The whole point of the MP7 platform is the 4.6x30mm. That's what gives it the armor penetration in a package that small.
Chamber it in 5.7 and you've got a CMMG Banshee with extra steps.
go_hard_tacoMAN@reddit
AU is full of shit as always. This is just to drive traffic to their website / email sign up
Minute-Log-7098@reddit (OP)
You're probably right about the listing. No US retailer has these in hand and there's no confirmed ship date from HK USA. I used the listing for the specs and price point and it's a placeholder, not an in stock item.
The confirmed info in the post comes from the BKA classification published March 13, 2026 and the Mike Holley interview on TFBTV from February 2025. Those are the actual sources, not the AU listing.
