May I suggest watching the show called "Flashpoint"? 95% of the time they're in their gear which includes thigh holsters (the original reason I started watching the show, then I absolutely fell in love with it and discovered a few more kinks I never knew I had). It is only 5 seasons (just ended end of 2012) but the ending is not a cliff-hanger. Anyways, I just wanted to tell you about an awesome source for hot thigh holsters.
I’ve seen a couple episodes - it’s a good show. Like you said, a good source of thigh holsters too. I’ll see if I can find a source for episodes…
Commander John Crichton - Farscape
Lieutenant Colonel Cameron Mitchell - Stargate SG-1
Oded Fehr - Resident Evil
Hondo (Joe Flanigan) - MHC
Supernatural Wincest NC-17 fic.
Summary: Sam has a thing for Dean in a thigh holster
