My girlfriend and I are seriously considering taking up hiking as a new hobby; however, we've been putting a lot of thought into the dangers involved. I personally am quite concerned about wildlife (mountain lions, bears, bigfoot, etc.). I know that the chances of ever being involved in an attack are slim to none; but I'm definitely not the luckiest guy around so I tend to take extra precautions. Currently, the both of us own Glock 19's (9mm) which I personally feel isn't up to the task of defending against a bear. With that being said, I'm looking to purchase a new pair of handguns for the sole purpose of protection while hiking. I've done as much research as I can on the subject and I'm considering either a Glock 20 (10mm) or a revolver in 357 or 44. Right now I'm leaning towards glock 20's due to price and familiarity with the glock platform. I've seen a lot of people that praise the 44 magnum, but I'm honestly not sure that I can handle the recoil especially during a bear attack. As for the the 357, I'm under the impression that the 10mm caliber is a "stronger" caliber for this purpose (please correct me if I'm wrong). The only issues with the 10mm that I can come up with is that ammunition may be hard to come by and that pistols in general aren't as reliable as revolvers. My knowledge on firearms in general is rather limited-- I've only been a gun owner for under 2-years. I'm hoping that some of you firearms gurus could give me a few pointers.
