Recently started carrying a BUG in an ankle holster, mostly for easier access when driving. Originally got it to try it out, maybe for occasional use, but it's so easy to carry I just started carrying it all the time. Wouldn't want to carry a primary gun that way, though.
FYI, I carry a 642 in a Wilderness Tactical Renegade elastic ankle holster, nondominant/inside.
Also, not LE.
