I don't even know where to go with this one . . .bmwrdr wrote:It may sound funny but a condom works well. I had the same issue while commuting on my motorcycle between KC and Dallas for ove three years. My problem was not sweat but simply water and if you ride a mc in rain and want to be able to get to your gun if you need it it will get wet. I carried my HK P30 either in the tank bag or in the outside pocket of my jacket in a condom. Simple but efficient, you'll be able to aim and pull the trigger.
I take a small .25 auto and put it in one of the arm band iPod holders.
