i have fired with a ppsh 41 and ppsh 43 too.the ppsh 41 fires well is you have a proper stance with it,do not grab the magazine when firing...left and just after the trigger guard and pull down to contrast the muzzle rising...if you use military ammo espect a good sound blast ...but the recoil is not heavy,,,when aquitance with the gun the hitting is good but beware of the long burst..
russian made large use of tracer ammo in war,to make easy the aiming in assault mode.when you aiming ,after made you familiar with the open bolt, is pretty ease hit a uman target until 50 m.
