I do a lot of mountain biking in the summer and this is my first summer carrying and mountain biking (G17). Do any of you happen to have any suggestions for methods of carrying while mountain biking? I have a kydex owb holster (does an instructors belt go with biking shorts??) I am anticipating problems with the belt & holster slipping or rotating around my waist. I also have a fanny pack that I have never used and don't imagine would be very practical since I would be bent over peddling like mad. A fellow mtn biker used a shoulder holster last summer, but complained of shoulder fatigue. Thank you in advance for your suggestions.
