Why not? Some people collect Matrix action figures, I collect guns. My collection is pretty small. Dude at my church has so many guns, he doesn't even know the exact number (he's got hanguns, assault rifles, sniper rifles, shotguns, and probably some other kinds too). Only difference between me and people who collect other stuff is that my stuff is kinda dangerous. It's all kept in a gun safe though, so it's all good.
