I've been retired now almost 20 years. When I was in uniform I had the Uniform shop seamstress line the left rear pocket of all my pants with a heavy canvas material that was sewed into the shape of my BUG which was a Colt Gov't 380 carried in condition one. The pants were of heavy weight wool so the 380 did not print and the bottom of the pocket was sewed to the pants leg so it didn't flop around as you walked. It was easy to access and didn't come out unless I pulled it out. If I was going into rough terrain I simply buttoned the pocket closed to prevent any chance of losing it. When I left I gave my uniforms to a new hire and he used a Walther PPK in the same pocket.
