Whenever I accumulate collector grade guns, my philosophy is to collect several of the same model that are shooter grade guns. Then when I have that desire to shoot a collectible gun, I just pull out one in "shooter" condition and fire away. I have found that that approach allows me to be steward of the pristine ones and still shoot the same models with all the thrill that entails. No guilt and all the fun! It also makes my collecting more fun...

... you get the picture. BTW - BOTH shooter grade guns and collector grade guns are great fun to accumulate/collect.
