I have the shield .40 cal. I also have a glock 23, which feels like a 2x4 now that I have the shield, so i'm gonna trade with someone for a M&P 9c for the glock. I went to the LGS to look at a 9c and I really like it. On the shield i can get a full grip with the small mag. With the 9c I can only get middle and ring finger, my pinky actually dangles off the end. I also tried the trigger because I heard there were issues with M&P triggers and although I felt some grittiness, it has a long pull and felt pretty smooth to me. I have fired my glock 1,300 rounds with 5 no bangs, and the guy i'm trading with says he only shot a few boxes out of it. Get the shield, you wont be unhappy.
