Wow!!! Very nice!A bit late to the show. Most of my 1911’s are full size or competition pistols but I still have three Commander size.
A Colt Combat Commander from 1973 is the early cut away inside slide one that was originally Satin Nickel and now finished in Electroless Nickel by Ron Mahovsky that has been refreshed a bit; Kart barrel, all parts except the thumb and grip safety are EGW. Sights are Yost Gold Line front and Harrison Retro rear.
The one with the black Alumagrips is a full custom build stainless and the one with the Summer Special 2 is a full custom titanium and my daily carry.
Titanium is only 1/3 lighter than steel so an aluminum frame commander size would be a few ounces less but I just wanted something different.
