Interestingly, I realized it after I picked it up and was in the car that the trigger was dead when I pulled it, the firing pin wouldn’t drop. Hmmm. Put the mag in and then it worked.

Funny because even after working in a gun shop for 2 years in college, I never realized that the M&P’s came with an optional magazine disconnect. I know all the third gens came standard with it, but I had never seen what I guess is a “gen 1” M&P pistol. Every one I ever saw in the shop, new or used would fire with no magazine, and had “pistol will fire with magazine removed” printed on the right side of the slide. Mine obviously doesn’t have that warning.

Learn something new every day, I thought it was broken at first. For the price I don’t care if it has the disconnect or not.
