I've had a Blackhawk Specops holster for going on ten years now, and like it just fine. The point made about universal holsters is well-made; you may find a holster made especially for your H&K that you like better. But all in all, the Specops is a great universal rig. It's relatively adjustable for different sizes and shapes of weapons, and you can wear it on your hip or slightly dropped onto your thigh. It can also be put into various configurations on webgear. I like the protection and security that the folding flap gives my weapon when ingressing/egressing vehicles and/or "moving with a purpose." I've used it with 1911's, M9's, and full-size Glocks, in some relatively rough environments, and it's stood up as well as anything else I've used. Once the flap is up (i.e. your thumping and bumping is done, and you need the weapon ready for quick access), I'm not a big fan of the velcro/snap thumbreak. I like to leave it in just the holster with friction holding it in (I've never had it fall out), and I generally use a retention lanyard anyway. YMMV.
