The best holder I've found

This tourniquet case is well designed and the tourniquet is well secured while in it. It’s locking mechanism holds the case securely to whatever it is attached to and has a double safety lock. Lastly, the case can easily be changed to allow the case to be positioned vertically or horizontally.

I recently acquired IWB and OWB holsters for a Glock 45 with a TLR-7 light. Both holsters fit the gun perfectly and are very comfortable to wear. The OWB holster is extremely slim lined and easily concealable. I would highly recommend both of these holsters for LE or CHL use.
I also received a TQ holder that is a great piece of gear. This holder will hold a variety of TQ's (unlike other holders on the market), i.e. Cat TQ gen 6 or 7, Sof-T, etc.
