For the longest time I had a 1943 Colt 1911A1 still in the Kraft box and looked unissued/unfired. Paid a bundle for it from the guy who originally bought it for $17 back in the early 60s. One day, I took it out of the safe and fondled it as usual, only this time I loaded both mags, one of which was still in the brown wax paper. I loaded them with ammo from a box of WWII vintage Winchester ammo. I shot both mags through that gun and it was a great feeling and I thoroughly enjoyed it. Then, I cleaned the gun, put it back in the box, and sold it on GunBroker for about 4.5 times what I paid.

Now I don't have a gun I won't shoot. I went through that "this is too nice/collectable to shoot" faze. Now, if I want to shoot something, regardless of how nice/old/collectable/rare it is, I shoot it. Maybe not a lot, but I'll shoot it.

Then again, I also don't care about holster wear on a nice carry gun.
