Recoil was not a problem......
I'm trying to remember what the recoil was like when I shot my S & W MP40. I've only been to the range with it one time and then only shot about 200 rounds. I remember expecting a greater recoil than my SW9VE and being pleasantly suprised. The recoil of my MP40 was quite manageable. Not the least bit uncomfortabe. When I returned from the range I told my wife, who usually shoots a 9mm a Baby Desert Eagle, that she would like shooting it. So, I guess the recoil is no big deal. :)
That said, I've only shot a 1911 45 caliber one time (about 5 rounds) and I agree it has an entirely different recoil. Now I know why 1911 fans are so fanatical!!!! :rolleyes:
