How good / reliable of a shooter is it ? Seeing that it's only $200, shoots a widely available round, and is based on a historic firearm, it looks very tempting. I do know that the grip angle is very different vs Glock I am used to, and it's a heavy all steel gun. But, is it reliable ? Accurate ? Safe ? Finicky with regard to ammo ? Hard to service / find parts for ? Easily rusts ? (Soviets were supposed to be using high quality steel but I an not sure about the Yugoslav manufacturers). Opinions ?
