I really tried to find a decent holster for my 7.5 inch Mamba ( Ruger Mark IV 22/45 Lite with all Volquartsen upgrades. A few companies now show leather holsters that will work but I decided to get out my leather and make my own.
It has two layers of leather and a felt layer on top. The tension screw is mounted under the trigger guard so that I can adjust it and keep the gun from falling out while moving. Even without the screw this holster is secure.
Any comments are welcome.
