Shoot them. There is no collector value for most Ubertis so even though they are unfired, they are "used" guns and won't bring as much as one you can buy new off the shelf right now.
That is true, but sometimes it's nice to have a few disply guns that have no rings, burn marks, or dings on them. I'm sure the Dragoon will get fired in the future, but the 1851 is just too pretty to shoot - can't bring myself to do it
I'm not a collector in the sense of monetary value. Don't ever expect to make $$ on any of my guns. I get the real value out of shooting, viewing, and passing them down to my kids. In that order of course!
