I'd like to ask a question first: do you mean models of weapons, such as a Glock to a 1911, or do you mean specific weapons, such as this 1911 to that 1911?
I have two 1911s that I carry, (one at a time) but I've gone back and forth, for different reasons. But it's always been one of the two 1911s, so in one sense, I've switched, in another, I haven't.
So let me know what you're asking, and I'll vote on the poll.
