Our Master Collection line of holsters are nothing short of the finest in gun leather. The Master Collection upgrade uses the same Hermann Oak domestic steer hide but in a thinner stock laminated together to keep the form factor and weight at a minimum. The end result is a double layered leather so that you have smooth leather on both faces creating a smooth interior and exterior to the holster. This also lends to the ultra detailed molding on the interior so that your firearm fits perfectly into the holster.
What is the advantage of the Master Collection upgrade?
First and mainly, it creates a smooth interior to the holster which helps with finish wear on your firearm... but it will not prevent finish wear. Finish wear on a firearm that is holstered is inevitable. Holsters hold your firearm in place with friction. When you draw or holster your firearm you are rubbing the finish at those pinch points. In short, it helps delay the inevitable result of carrying a firearm...finish wear.
Second, you may experience a stiffer holster. Because of the lamination process, the more layers of materials with grain running in different directions coupled with cement securing them together results in added strength. This may require a little more time and effort during the break-in in process.
