Colt lightweight carry gun with well North of 100,000 rounds through her. Fourth barrel and I had to use a ramped one as the feed ramp had been worn down, welded up and cut back too many times.
She ate mostly my own rolled 200 gr RN and loved them.

Replaced her with exact dup only in 9MM, using Caspian frame and Kart barrel.
Tried to make all the parts and pieces, even the sights the same so I had no retraining to do. Recoil from the 45 was beginning to bother my hands after 3 to 4 hundred rounds a weekend. 9MM is not so punishing and still very effective.
