Sig p227

[commando552]

I wouldn't even call the P227 a double stack, it is more like a one and a half stack. I imagine the reason it has such a crappy capacity is the fact that it wasn't designed really as a double stack .45, but rather built around the .45 magazine for the P250 (I think the base plate is changed for no reason just to make them incompatible) which was originally made as a 9mm.
