Here's my experience (for what its worth).
A few months ago, i managed to get a 1905 Peacemaker 45C at a local auction. Its beautiful, about 50% - 60% original blueing, miniscule amount of pitting, original stag grips, and a holster that i believe is about the same age. Most of the blueing that wasnt on the gun looks like it is now embedded in the leather inside the holster.
Its a purdy piece alright and cos its all original, i was a little worried about shooting it. Hey, I may damage it, and i didnt want to ruin a truely collectable piece.
So... what did i do?
I went out and bought a couple of packs of cowboy loads and went down the range.
Why? In my mind, the chances of me stumbling across something like this again in not even worth putting money on. Like most of us, I grew up with toy cowboy pistols and always dreamed of having a SAA. Now, I had one in my hands. What else could I do buy go out and put a couple of boxes through it?
OK.. its now up for sale again, and I am gonna make quite a substantial profit.... which is gonna fund two gauchos, a 97 pump and a Henry. BUT, I got to handle and shoot a dream gun.
Bottom line.
If its not 'irreplaceable' then you should at least go out and have fun with it. If I hadn't taken the SAA down to the range and enjoyed it, I would have regretted it for a LONG time. Yeah.. i could have just bought a Ruger, or a Gaucho... but.. its just not the same is it?
Guns were made to be shot. If they are in such a bad condition that its dangerous to put some rounds through, or if they are true 'treasures', then they arent 'guns' anymore but lumps of metal.
my 2c worth.
