I don't carry either of those pre 80 Combat Commanders. These days I have a 2013 Colt/Talo Clapp Commander I carry.
With mine the 82 is in superb shape plus the fit and finish is very good. It also has a nice trigger. I traded it to a friend who is very much into revolvers for a Ruger Blackhawk in 45 Colt I bought about 2002. The fellow had barely shot it but sadly threw out the box etc. a couple years after he bought it. It gets shot every now and then but not a lot.
With the 1980 I was looking for an a pre 80 Series for a project I had in mind. With it the fit and finish looked good in the LGS. They were O.K. with me field stripping it in the gun store. After cleaning, lubing and putting about 50 rounds through it for function testing I detailed stripped it.
I knew this pistol had a very nice frame to slide fit etc. It did have a not great trigger, but that didn't bother me. What surprised me was I think someone already had put in a new barrel bushing and link pin. Very close fit on them. I put in an EGW trigger pull reduction kit with the exception I put in a new black Colt Defender hammer. I also put in almost all new springs. I put in a new Titanium Colt firing pin and new stocks from Altamont. The arched steel MSH was replaced with a flat one sourced from an old Gold Cup. I also fit a new long trigger from Harrison Design. So today the 1980 looks like this.
The last step I have is to put dots or something on the small sights, which I want to keep on the pistol. I bought a Plano pistol case and put all the take off parts in there so I or a future owner could return the pistol to pretty much how I bought it.
