That new STG-45 in .22LR.
You'll never own a real one. I've handled and shot a real one. The .22 version, aside from a tiny weight difference (maybe a pound?) and the mag having a slot in it, is a clone.
They're also fun.
"And Shepherds we shall be. For thee, my Lord for thee. Power hath descended forth from thy hand, that our feet may swiftly carry out thy command. So we shall flow a river forth to thee and teeming with souls shall it ever be. In nomine Patris, et fili, et Spiritus Sancti. Amen."
