Those little SMGs are fun, two things to keep in mind - don’t put your hand or fingers near the muzzle, and watch for the barrel rise.
And have a very large wallet.
Sub-guns are fun to shoot. Expensive, hard to control until you master the burst, and exciting for most shooters.
My favorite is the PPSH41. It is the most controllable of them all and it is the cheapest to shoot with surplus ammo.
I wondered why they didn't put a Cutts compensator on them, especially for fully automatic.
