I got into 40's twenty-one years ago, have several, reload for it, and am satisfied with it.
I bought one 45 a couple of years ago, love it, been reloading for it.
I've been TRYING to sell off calibers where I only have one firearm. But it's not like the good ole days when the government was scaring the hell out of everyone and firearms sold a bit easier.
So as much as I like the 45 caliber, I'd like to simplify my life and stay just with the 40s.
