My leather riding jacket has an inside pocket that holds a small semiauto (flat, which I hope will hurt me less than a J-frame when/if I hit the ground. I've used an appendix holster on my former Norton, which was a more agressive riding position. I've used an Uncle Mike's shoulder holster and white it worked, I didn't like how it carried. I think I'm going to get a really good shoulder holster and try that myself...
