I have a Draco pistol, has an eleven and a half inch barrel. Has wood instead of the rail system the picture has. Fun to shoot you need to learn to point shoot but with a 30 round mag or a 75 round drum you will learn to point shoot fast. Recoil in easily managed, heat of barrel when shooting a lot of rounds is biggest problem. They are extremely loud, you will be noticed at range.
Mine is a Romanian has a Crome lined barrel, takes any AK 7.64x39 mag.
I say go for it great truck gun.
