I don't know if anyone else has had trouble finding these, but I've been looking forever. Looks like we finally have another option besides universal holsters, or holsters actually made for the USP, but sort of work for the HK45. HKWEBSHOP
I love my Galco Miami Classic 2.. In a pinch you can also use a Galco Concealable holster for a Glock 21
Mostly wanted something for comfortable open carry out in the woods. Have to be able to climb, bowhunter, as well. Bought a cheap universal thigh rig that'll do for now. I like the idea of how the Serpa locks the gun in place.
Good point, hadn't considered something blocking the locking mechanism, and for my puposes things will be getting in there. Makes me feel like maybe I went the right direction with the thigh rig.
