Hello everyone, so im about to purchase a Derya ZY9 B6-10 CH101 5.9" but im also a bit concerned that i cant find a lot of information on Derya. Are they reliable(the firearm itself and Derya as a whole)? Do they tend to malfunction? Thing is, its a real pain in the ass to obtain a permit to buy a firearm in Bulgaria so i dont want to let it go to waste with a shit firearm. My options are limited because the law states that for self defence purposes the barrel lenght of the firearm cannot exceed 30 cm. Any information is appreciated, especially from someone who owns one, thanks
