I have (estimated) close to 5000 presentations from my BH CQC Serpa holster that rides on my body armor. I have yet to have an issue with this holster. Matty is such a gear snob... if it isn't white, like his shoes... he won't have it.
Seriously though... I do like the BH platform, the way it rides on my leg. I can get it very high, up on my hip almost. I also like the fact that with just three screws, I can change my holster to any gun that I have. I have one for my 1911, for my Glocks, and for the Beretta.
The regular tactical serpa that BH makes, has a higher "hood" in the front of the sight rail, but the CQC does not have this hood. It has the same retention system... and IMO it is just as secure. What the "hood" does, is protect your rear sights a bit better, by having some plastic up a bit higher. I don't use this holster, since I do not do patrol work.
Most of my time is spent in a shoot house, using a Glock 17T with SIM rounds, force on force. I am getting VERY used to transitioning from my M4 over to my Glock, from the body armor.
For what I am doing, it really works. But, I also like the Safariland leg rigs too. I would say, the VAST majority of the LEO's that come through my courses, are using the Safariland. I have seen a few teams kitted with the CQC stuff, but not many.
I am getting so comfortable drawing from the CQC Serpa, that I am using it in some stages at my local shooting club. Most of the guys look at me like I am nuts, using a "retention" style holster, in a stage. But, I find it just as fast as my non retention FOBUS paddle.
I guess it is all in how you train with your gear. I would be interested to hear about the CQC stuff, and the problems you are having or had with it Matty...
In all truth though, I really listen to those out there on the tip of the spear. It's been a while since I was in the box, so things have changed. I don't have any other BH gear, save for the CQC holsters and a Gladdius light. BTW, the strobe feature on that light is worth it's weight in gold!
