OK, kicking this thread back up there...
What is the oldest firearm that you currently own, that you would and actually do, trust your life to? Something you've fired more than 50 rounds through in the last year. And no, I'm not talking about Grampa's .30-30 that you whip out once a year to hunt with, or that SKS that's still in the Cosmoline. If you do have those sorts and actually rely on them as a primary defensive tool, please share as I find that sort of stuff much more interesting than the latest "tacticool" black rifle or tupperware hog-leg. Real stuff that get's real use, even if it's just a truck gun you stash under the seat.
My oldest is probably a blued 1976 Colt Cobra in .38 Special. If I'm wearing pants, I'm probably carrying it. I've left it stock as I just like the feel of the craftsmanship. Honestly, it's so smooth from years of use, it really doesn't need any work. My next oldest are from 1993, but those aren't really anything interesting or noteworthy.
Anyone else?
