No, I don't own one. Shot the crap out of deepwater's. However, in response to TAB, whether it has expanding ammo or not, some rounds are still effective.
Not many,... however, if all I could carry was non-expanding ammo, it would be .45ball. The military still sees the 9mm ball as "good enough".
But for a glove box pistol, tool box pistol, a back up in a BOB, One that can take a ding or a scratch, be exposed to "less" than ideal maint. conditions, and be cost effective, it is an option. Not for my personal carry, but to have one around, with a pile of ammo and mags, isn't a bad thing. I'll get one of my own just the same.
Especially when you see "some certain" types of folks at gun shows buying body armor these days.
