The Ruger Sr1911 commander in 9mm carries flat and after day 2, you just don't notice it is there. I looked at it in .45, then I compared ammo prices. I can shoot the 9mm a lot more. Ballistically, they are both pistol cartridges, and you can carry a couple of more 9mm than .45. The original 1911s were available in a lot of smaller calibers and a few bigger.
I like it, so I bought it. Tastes vary.
Wife was surprised. She first saw it when I showed her the holster I made for it. Gun was in the holster, and I never mentioned the gun. She almost said something, but wasn't sure.

Every man deserves one excellent gun, one fast car, one great dog. I had a fast car when I was a kid, I have a great dog now, and this is the best of the two guns I bought new.

Garand was designed as a .276 cal rifle.
