I voted for the .45 FPC. I just prefer .45 and since I own a bunch of them I have lots of .45 ammo on hand. If they offered a .45 FPC I’d buy one, and a M&P .45 pistol to go with it. I’d also definitely buy a .357 Sig FPC, but I know that won’t be happening. I will also second the request to include iron sights with the FPC. It’s not asking too much for the gun to come with simple iron sights so a Luddite like me can shoot it right out of the box.

Two of my friends have the 9mm FPC, and both purchased M&P 9 pistols to go with the FPC because the mags work in both. S&W is certainly selling a bunch of the FPC’s based on how fast they disappear off the shelf around here.
