"From Russia With Love was being aired last night, and reminds that Bond did it ideally: a lightweight setup that slips on and off readily and can be worn with absolutely anything as long as there is a covering jacket. His could just as easily have been a little horizontal except with the film holster's very crude construction (it appears to have been copied in fabrics from a Heiser vertical) a stap would've been required a la Gaylord; and so problematic for a film. For the revolvers the Berns-Martin would actually have been excellent, hence the recommendation from Boothroyd (and I notice that "Q" is still called Boothroyd in this second film): small and light with a Smith Bodyguard or Centennial in it.

Harnesses: although I agree with Ray about the requirements of harness design, NO ONE makes such a harness. In the end they are either a simple arrangement of straps like a Galco or a Berns-Martin; or the equivalent structure with lots of curves (such as a DeSantis or an Alessi). It was the increase in pistol weights that caused any of us designers to even consider the harness because, as mentioned, they were supposed to be for small pistols (the old Colt SAA spring holsters of the Old West notwithstanding).
