My favorite government model, just realized I have been shooting mine over 30 years. Went back to Colt a few times for mods andfixes. I have many, many thousands of rounds thru mine. You picked up a great pistol there.
I've wanted one of them Combat Gov't Models. Years ago there was a used one for sale at a LGS, and boy I wanted it. A friend and co-worker did in fact buy it, but it got stolen.
But what I did do was pattern my Series 70 after the CGM, using KINGS hardball sights.
