I got to go to the NRA show last year and talked to one of the S&W reps. I asked about a M&P .22 handgun and the likelyhood of it happening. The rep said that he thought it would be a good idea, but that it wouldn't be happening anytime soon.
I know that they can't give away info on products they are working on developing, but still......
I will probably have to buy one of these to go along with my M&P 15-22. And that will probably lead to a M&P in .45 which will lead to an M&P 15, which will lead to.......Oh boy it never ends does it!
