I have had my shield for 4-5 months now. Love it. I have out about 800-1000 rds through it with no hiccups of any kind. Cheap federal, win, blazer. It performed well.
Love the trigger. Took about 450 rds to get here but it is nice. I am considering a M&P9 also but the trigger has no reset. I guess I shouldn't get hung up things like that.
Just bought a M&P22 at my lgs yesterday and it also shot fantastic. Shot about 300 rds last night of superX. Some ****ty ammo but gun did good.
My 13 yr old loved it.
