I have long been a fan of the lightweight commanders, and I currently own a Springfield lightweight GI mil-spec. I prefer the lightweight models for carry but I have had a few problems with the alloy feed ramps getting beat up, which is one reason I bought the Springfield which has a feed ramp on the barrel.
However, I just purchased a Kimber micro 3 inch gun, and it hasn't missed a lick yet, so I quickly growing very fond of it, for a carry gun.
