A special combination of polymer is used in the construction of the ShapeShift Modular holster to increase durability and guarantee that it will last the lifespan of both you and your firearm. We guarantee that the holster will endure hot weather by using polymers that are comparable to those used in the manufacture of weapons, in contrast to many other holster solutions that may distort under such circumstances. And in the unlikely event that something does go wrong with your holster, we offer a lifetime warranty on every item.
