Looking to get a 40 or 357 sig M&P, and from what I have read the factory barrels can just "drop in" to swap calibers. Obviously I would need 9mm mags, but is there any issue with reliability, or other things that I am missing? For carry it would stay in either 40 or 357 (to be honest .40 doesn't do much for me, I love 357 sig though).
Anyone tried this?
