Just went out and shot my .40 M/P this morning. I've had it over a year, but really havn't had a chance to shoot it as much as I like. It's getting broke in kinda slow. Probably have about 600 rounds thru it so far. It hung up and jammed when I feed it semi wadcutters. Not all the time, but had about 4 hang ups out of about 60 rounds. Mixed up round nose,hollow point and the sw. And, not every one of the sw jammed. I had 20 rds. of the sw to get rid of. I have since switched over to a truncated shape bullet, and they feed well. I'm liking the gun more and more, I shot it. Hopefully now that the weather has broke, I can get down to the gun club and get more range time in. gypsyman
