Crude, ergonomics of a 2x4 but they shoot ok and ammo is dirt stinking cheap. Think of it as the great great grand daddy of the FN 5.7 fabricated from an old russian army truck spring using nothing but hand tools and a serf powered drill press.
If you want a decent commie pistol get a makarov or one of the polish or czech derivatives. They're a lot nicer and 9x18 ammo is cheap. I bought a makarov a few weeks back brand new for $180.
