A new standard is being set for comfortable carry with the new ShapeShift Sig P938 IWB holster. No other holster company offers a holster with the same capabilities of adjustable retention, the same comfort and easy concealment as Alien Gear. Where a good number of P938 IWB holsters are found wanting is with the retention shell. The ShapeShift shells are unlike any other on the market. Unlike most plastic retention shells which are press-molded over a form, these shells are injection-molded using a proprietary ultra-durable polymer. Unlike other shells which can break or crack due to a brittle plastic, this will not. Other holster companies ask you accept the retention level their holster design imposes. Alien Gear does not, the ShapeShift P938 inside the waistband holster has fully adjustable retention. Set it exactly how you want to. The ShapeShift 938 holster is also designed to carry more comfortably than any other holster. The top layer is Alien Gear's proprietary Alien Skin fabric, and the core is a spring steel flexplate. This aids retention and enhances comfort. However, the backer has been streamlined and downsized, making it far easier to take on and off. Just like the 3.0, the ShapeShift is also compatible with the Cloak Dock IWB holster mount system. You can use this docking system to create a holster dock on any surface you wish to attach the holster to. For life. That's how Alien Gear does holsters.
