Like a lot of you I've got a CCW permit, but I only carry occasionally. I've thought about an ankle holster, but using that front right pocket in my jeans seems like a pretty darn handy place for my little J frame. It is a hammer model, so I suppose that it could snag, but it seems to me that a confrontation out on the mean streets wouldn't be a fast draw situation anyway. Having it along anywhere beats not having it with it home in the drawer.
In the early 80's when I worked for Bianchi, we sold a set of J-frame grips that extended up the back of the frame and acted as a hammer shroud. It basically turned a model 36 into a model 49. Unfortunately, I haven't seen any for sale at gun shows for years, but they were a good attempt at making hammer guns less likely to snag.
JMO-YMMV.
