For those who carry concealed, on body, while motorcycling. What's going to happen when you go down? While bicycling I carried an AMT 380 SA Backup in the back pocket of my jersey. I went down and while I didn't land on the pistol, I did roll onto in while coming to a stop. It hurt, and left a very nasty bruise right over the spine. I decided that wasn't a good idea.
Tried a few thing most of which couldn't be reached. Then I found a small triangle pack that attached to the seat post and upper bar. Size was perfect, just undo the zipper and the pistol was easily reached and drawn.
