Hi all, Heading back to Alaska for the summer and considering anti-bear carry options. Last year's solution was a 4" 500 S&W in a Diamond D Guide's Choice chest holster. I wasn't extraordinarily happy with that setup, as it was very heavy and the leather stretched a bit after 10 miles of sweaty hiking. This year's gun is a Glock 21 with a 460 Rowland conversion. I'm considering a Kenai Chest holster, I like the nylon and kydex construction. Are there any other options out there? Am I missing anything? Any other recommendations?
