Definitely would not use a suppressed mounted Glock concealed unless it was in one of the Army Custom pivoting shoulder holsters that a Special Army unit was testing awhile back with a SWR suppressor.
I would only use the Crye Glock holster on the belt with light mounted and not with suppressor attached in concealed carry. The snap latch allows proper secondary retension for security, and since it rotates on an axis, you can adjust it to cross draw or for when in confined spaces like seated in a car.
I see it as a novel approach to a design request by Crye's Special Ops customers for a special Glock holster.
When I was in the Navy, we used Bill Roger's breakfront kydex holsters to carry H&K P7's during an early testing protocol, but the Beretta pistol was accepted instead of the P7M8. This Crye holster reminds me of that time.
Now if they started cranking out the holster for the H&K 45C.......I think I would be much happier, but I am not a Navy SEAL.....so I would just have to wait.
Pictures to follow.
