As a competitive shooter, I'm shooting master or expert class with several different guns.
As a hunter, I do pretty good, not much gets away if I get a shot on it.
As a collector, I own guns that I do not shoot and I shoot rare guns as well. I don't see a problem with collecting rare guns and not firing them or somehow diminishing their value. Would you insist on shooting an aluminum cylinder Air Force issued Aircrewman just to prove you could?
When you hear those bubba stories about some Fudd who ruins a hard to find old military rifle or drills and taps a post-war S&W and makes it a near worthless shooter, it is mildly sickening. I have a post WWI commerical Colt 1911 that some geezer had a gunsmith put cheap sights and a replacement barrel in,,,,,,,,,,,,,,ruining the collector value.
Two things come to mind.
1. Where did he find this lousy gunsmith? He took a $2500 gun and made it a $400 dollar gun. He could have sold the thing and bought a Les Baer or Wilson Combat and got far more gun. Instead he actually paid to ruin it.
2. Sure it is YOUR gun, you are free to do with it whatever you choose. Why would you think it makes you look intelligent to ruin a valuable collector's item? Worst of all, it rarely becomes the "huntin rifle" or in this case,,,,,,,,,,,,combat pistol, you were wishing for.
