Shoot, I buy, sell, trade, and swap them all the time. They're just things, meant to be bought and sold. I don't get emotionally attached to them.
I do the same thing,whenever something different comes along,
old or new. I'll trade a gun in to giver her a try.
I have a core group of guns that I won't likely trade---BUT WHO KNOWS!
Most are "play things" for fun. I've gone from revolvers
to autos back to revolvers and now I'm in to six shooters and lever
actions that shoot handgun bullets.
