Want some irony?
My all time favorite - my chips are down go-to gun - last one I'd part with before the long dirt nap -
A Smith and Wesson Model 19 -4 w/a 6" barrel.
The irony is that it's a .357 magnum, which is near the bottom of my list of favorite calibers, right down there with the .25acp. Honestly, I have little to no use for the .357magnum,,,,not to say it's not one of the "Great's of all time",,just that I have little or no use for it.
