Well, your post was a good one to renew, because some wonder whether that would be an issue. One thing for sure, it's OK here in Wisconsin and perfectly legal to carry while on/in a motorcycle, automobile, ATV, UTV, bicycle, snowmobiles and even roller-blades.Wow, thanks for bringing this old thread back to life. I had forgotten all about it but now I can follow up and attempt to get things back on track...
When I ride with my Security-Six, I currently use a vertical shoulder holster that a local leather guy made. It is nothing fancy, but it does the job well (securing he revolver and staying conceled) as long as I wear a jacket, sweatshirt, or some other overshirt.
If I decide to carry my SR9E, I use a Vedder LightTuck Kydex IWB holster. Of course, to conceal it I have to wear an overgarment of some sort.
In the warmer months when I ride in just a tee shirt, I've been using my Smith and Wesson Chief's Special in either a pocket holster or an ankle holster.
Thanks to everyone who has contributed to the original topic since my last post back in 2017. I appreciate all of your suggestions and comments.
And although my rear doesn't get anything like the rear in the photo posted, I can tell you that Anti-Monkey Butt works well, especially on those long rides.
