Is this going to be a year round concealed carry .45?
I have a Sig 220, a custom Commander, a custom 1911, a Glock 21 and Para p14. Obviously, the last two can be scratched off the list as they are too big for concealed carry unless you are on the north pole and can wear a thick parka all summer long. A single stack 1911 can be concealed fairly well even in summer with the right holster. The Sig P220 is close to commander sized but to me it feels bulky in all the wrong places when I carry it concealed. That usually leaves me with my Commander .45 mated with a Milt Sparks Summer Special IWB holster.
I looked at a Kimber Super Carry Pro yesterday and liked the feel of it. With the aluminum frame it is only 28oz which is very noticeable when compared to a steel framed Commander. Kimber puts a "shoot a little, carry a lot" disclaimer on it due to the aluminum frame.
Pic of my steel-framed Commander and Milt Sparks Summer Special holster (finish is hard chrome except for the hammer, sear, hammer pin, sear pin and series 80 components which are gold titanium nitride. It started as a Colt '91A1 Commander...now the only parts left from the original '91A1 are the slide and frame).
