if you use a galco ankle band (i think it was) dont use an all steel J frame. those holsters with the elastic only retention must be made for the airweights only or something.....had a local deputy "loose" his (640 .38) during an officer survival school....well he found it because he stopped running to pick it up as he felt it fall out of the holster.....he doesnt use that holster any more, and it didnt look like the elestic one shown above with a strap across the trigger guard, this one (i said galco because thats all i could think of) looked like a J frame holster with a small elastic opening at the top to stuff the gun in. maybe it was worn out?
