I had started a thread about the Corps Of Engineers currently reviewing their carry ban, and that thread got side-tracked about holsters for mountain biking (since some mountain bike trails are on Corps land and I mentioned looking forward to possibly being able to finally carry on Corps land when I ride). I had a big part in that side-tracking, and the thread got stripped down to just the original part of the topic. I wanted to add here some of the info that was removed. Someone asked what type of holster I use when mountain biking. I mentioned Hill People Gear chest holsters this link: http://www.hillpeoplegear.com/Products/CategoryID/1 I have one (I like the Snubby one), one or two other users here do as well. Their stuff is highly regarded as solid, quality gear (expensive, though). You can also put your wallet, keys, etc. in a pocket separate from your gun. I also carry in a Blackhawk Serpa CQC. I like the very positive retention of those. If I crash my bike or fall off of my stand up paddleboard, I don't want my sidearm going flying (or sinking). I crash often, and fall off of my paddleboard fairly often. Normally, I don't want to add another step involved in drawing my weapon (pushing the retention button), but I feel that step is a worthy compromise to avoid my gun unintentionally leaving the holster because of my activity causing it. I started this thread, in case other people like those types of outdoor activities and wondered what kinds of holsters were good for that. Please add info about other holsters that you like for mountain biking, paddling watercraft, etc.
