GHD (Col. Guy H. Drewry), try and see if the chambers will accept .38 S&W, although simple reaming was most common, sleeving, swapping and about everything happened. You still have a .361 barrel. Correct grips are smooth non-medallioned military (plowhandle style).

No +Ps, if it is a simple reaming expect bulged or split cases.

Best wishes,
former O-3 guy
