Hello, I'm new to the thread and new to the M&P world. Purchased my 1st and new M&P 45 and shot it the next day. No mods, just cleaned and lube. Noticed that I was shooting low. Shots was not off, they were in the middle but 3-4 inches low @ 7-10 yards. Front sights were inline with rears. Asked the range officer to shoot a few rounds for me and he had the same issue. Took it to the guy at the front counter (he said he was the Smith and Wesson expert), he put a few rounds thru it and he was getting the same result. He said some shoot high and some shoot low. He told me to lolly-pop my front sights with the rears to get it on target. Is this normal? I'm in the military and have many years of shooting experience, but like I mentioned, I'm new to the M&P world. Any suggestions, advice would be greatly appreciated.
