Works if you want to stick with "tactigami" - Vertx MPH Sub Holster

I had issues creating a smooth pull while also keeping strong retention. The nub that can bee shaved down really works. It is a piece of rubber that indexes with the slide port. Looks like I'll need to shave off more than antyicipated to find a happy medium. Looking to switch the a 1/2 kydex half leather or hook-loop holster for use in the hidden compartment on the Vertx backpacks
