I remember that back in the 70s I obtained a firearms certificate from the local police for "personal protection on active service" and wore my Colt 38 auto in a shoulder holster under my flying suit in addition to the Browning on my waist. This was later replaced by a 357 magnum snub-nose. Now that was an equaliser! Never used either but they were great comforters. Only gun I used in anger was the trusty 30mm Aden.
Bet you cannot do that now!
