I shoot USPSA Matchs looking at getting a M&P Pro Series 9mm a guy at my local club told me that his on the first day out of the box would not go to slide lock then when it did would not release from slide lock. any one out there have this problem and if so was it a easy fix just want to know before i spend money or i'll just stick with my Springfield

I'm also looking at getting a model 29 any advice on this gun? (Dirty Harry's model right?)
