OK - I just got out of a 12 hour CPL class (I have 4 hours of range work to do) but the instructor had a SW J-Frame Airweight SPFLD that would fire 38+p. It also had an after market crimson trace grips with a round butt. The instructor challenged me to tuck it inside my belt, in the small of my back but near my right hip. I forgot it was there!
