I'm not sold on the SERPA mechanism yet, but I do like the other BH CQC products, I think the regular CQC holster is a pretty good rig.
I use them mounted to the underside of my desk & end table to hold a handgun out-of-sight. They work pretty well for that. I'm not a fan of Kydex for carry, I like leather for that.
I've used the SERPA for my last two deployments....never had a problem with them working--I used a belt holster and a chest-mounted rig...will use it again on my next deployment.
ETA: While the SERPA is a good retention holster, it is not conducive to deep concealed carry in warmer months. It would be a good holster for winter (covered by a coat/larger shirt) or open carry.
What is the purpose of the holster?....CC or OC?
I like them. I have one for my G33, it works well for the G23 as well. I can hide it under a loose shirt, though not always easy.
Keep in mind the "LH" stands for "Left Hand", which isn't that good if you're right handed...
Here's a picture of mine (RH) in crossdraw. The system allows for a lot of custom configuring. It works very well, but it does stick out just a bit more than I like.
Would I buy another? Sure would.
Thats the first holster I bought for my 1911. I never use it now. I don't cc my 1911 much anymore. And that holster sticks out to far for me.
