If your Holster has a thumb break/ retention strap: You may need to stretch the retention strap before you get it to snap. With your fingers only (no tools, water, chemicals, or etc.). You may need to break in the holster first by using the 6 simple steps above.
- Place your UNLOADED firearm in the holster.
- Hold the firearm grip in your dominant hand and the thumb break strap/retention strap in the opposite hand.
- Prepare the strap for stretching by grasping the snap and pulling the strap firm (remove the slack).
- Twist the strap about 90 degrees back and forth in a clockwise and counterclockwise rotation about 10-15 times while keeping it firm.
- Firmly push the firearm away from you while pulling on the strap and continue rotating the strap.
- Release the tension for a moment and repeat 3-4 times as needed.
- Pull the strap over the back of the firearm without releasing tension.
- While maintaining the strong tension attempt to snap the retention strap closed.
- Repeat step 5 and 6 as needed.
Following and repeating the above instructions is the only way to an ideal break –in and long service life and proper fit that will last many years. It is common for the inside of the leather to scratch from a single holstering, that’s known as etching. A smooth leather lined holster will be even more subject to this normal occurrence. After this initial etching, the holster will custom fit your firearm. When testing out MTR Custom Leather products for proper fitment, never place a loaded firearm in a holster without first testing. Should any MTR product become worn, loose, broken, defective or ill-fitting, or in your opinion is unsafe, cease use immediately.
