last time I went shooting like that is was skeet shooting with a 20 guage. that's why I asked you about the shoulder thing, cause mine sure hurt after skeet shooting! I'm guessing a mp5 is a pistol, not knowing.
I did the skeet shooting, and after about 100 rounds, firing the gun was not pleasant. I had a giant bruise on my shoulder. Over an afternoon, it became less fun....
This is an MP5
800 rounds a minute, so we won't be spending too much range time with it..
