So, I figure this one is bound to come up. I'm trying to decide between a 1911, likely a Springfield TRP and an M&P 45. I have the 9mm full size M&P but really want something in 45. It seems like the 1911 might be more concealable due to a flatter profile and everybody I know who has a 1911 says that they are nail drivers and about as accurate as a a semi-auto can get. On the other hand, I have no complaints about the M&P. Any thoughts on this one?
