Let me start off by saying hi!...my name is josh in not new to firearms but I just purchased my first handgun. I've been researching for a long time and i decided on a fullsize M&P 40. I was dead set on getting one but this weekend I went to a gun show and walked out with a 9mm shield. So far I've put about 150 rounds through it and im not disappointed with my decision. but I was wandering what everyone else thinks about the 9mm sheild. Please let me know if there is anything I should look out for......THANKS.
