I got interested in shooting, so took a local two part class on the basics that started in the classroom and ended on the range. In between I stopped by the gun shop to get a gun. I ended up with a S&W MP9; in part because one of the backstraps made the gun feel fantastic in my hand; in part because the salesman strongly endorsed it even over more expensive items. (Which maybe means he really like it, or maybe means that he got more commission on a cheaper item.)
I'm a horrible shot, but the gun seems fine.
No jams, recoil seems totally benign. The trigger reset had an odd two stage feel at first, but seems to have smoothed out in the first 200 rounds fired through the gun.
I just need to get better hearing protection or get used to all the loud noises involved in shooting. Makes me jump and with live rounds I'm still milking the gun half the time in anticipation of the loud bang; even though dry firing I'm rock solid. As a side note, I can also endorse exercises with fake training rounds to expose one's mistakes with live ammunition as well as a good instructor for identifying one's problems.
Anyway, was looking around on the web and found you folks. Wanted to stop in and give a new person's impression of the MP9. Seems to shoot bullets just fine.
