I have nothing against custom guns. I admire many of them. However, I'm a collector of sorts, and often see guns that have been altered in such a way as to never be able to be "original" ever again. I learned many years ago, that collectors prefer things to be as original as possible. A wise old gun collector once told me of how sad he felt everytime he saw '03 Springfields chopped up & customized. He bought as many originals as he could, and stored them away. Well, a few years back, he began selling a few of them, at a seriously good return.
So, if you have a "special" and it's not the only one you have, why alter it? Get a beater to shoot. Or use others that aren't special. In my collection, I have some safe queens and some shooters of the same models. It's easy that way. One day, maybe my family will enjoy the rewards of my collecting. And the shooters will be appreciated by those that get them as well.
