I know they have quite a following but I attribute that to their cost and cheaper ammo. I find them unshootable. A friend owns one we took out and while he tried to use a charger to load it he took the end skin off his thumb...that looked like it hurt. I shot a few and gave it back. He didn't go much further. I would have owned an SVT 40 though if we didn't have such foolish magazine restrictions here. The cartridge is potent enough.
