KY Jon has the right idea. Have several dozen guns of each type in different gauges and barrel lengths to minimize the damage you may do with excessive use of each gun. Several dozen of each type is only the minimum, not the upper limit.
The Preacher has an even larger collection of gun pictures. And you cannot damage a picture by shooting it too much. Nor do you have to clean it or worry about what hinge pin grease to use. You don't need a big heavy safe to store them, and there is no need to insure them againt theft. You don't even have to worry about anti-gun Democrats banning or confiscating them... yet. But you can post those photos here all the time and pretend to be an internet gun expert. Talk about a win-win situation.
