Well, even if he doesn't ever use it in the sense of drawing it or firing it, he clearly uses it for peace of mind. Some people also carry a St. Christopher medal for a similar purpose. When a 'personal protection firearm' gets used for any other
purpose than peace of mind is when I become concerned.
Hey, I'm a Methodist but I have a St. Jude medallion I carry on my pack. He's the patron Saint of hopeless causes. I've felt like a hopeless cause on a trip or two.
And while I might not take a Glock (I carried a Smith Model 58 .41 Mag. in the mountains....once) I might consider carrying a light and thin Ruger LCP.380 these days. Not for bears, but for, uh,'other' predators. Less than 12 ounces loaded.
