I was considering that the Combat Commander had a 3/4" shorter barrel, and would be easier to carry. And, I would certainly agree that if you have never shot a properly tuned Govt or Commander model, you don't know what a good semi-auto pistol trigger is.
The 3/4” shorter length is not really significant. The 8 oz of weight loss is VERY significant. That Commander sits on my hip in a pancake-style holster all day and I don’t even notice it. A full-size steel frame - I notice it. Kimber now makes a full size with an aluminum frame. I just had to get one and it is sweet!
