I don't rotate EDC... ever. And the reason is extremely simple: I am a real handgun enthusiast and handguns are a visceral experience for me. I
love 'em and have a blast chasing down the guns I really enjoy.
It seems to me that the ones that are best suited to personal defense carry... are guns I don't otherwise enjoy. Or, at least enjoy nearly as much, and not at all in the same way.
So I have a fine defensive gun and
EVERYTHING else I chase, buy, love, shoot and enjoy and dote upon are fun guns that I love.
So I keep my Glock for carry and I practice with it, but I have no desire to chase down any other tupperware because I don't like 'em. Soulless, passionless tools that might just as well be in blister packs hanging from a pegboard in a hardware store.
And on the flipside is just more to back up my game plan-- the guns I truly love and enjoy the most will get regular use from shooting and cleaning, but I am not comfortable with banging them in to door frames, sweating on them, filling them with lint and filth and putting them through the finish-wearing rigors of daily concealed carry.
I don't ask or expect others to agree, but it does work for me. Same Glock 29 at my side right now... as it was in October, 2008.
