Concealed Carry Glock 17 Holster Our Glock 17 holster was designed and crafted using our high-tech proprietary process to exacting specifications. We’re so confident in our Glock 17 IWB holsters that we back them up with a lifetime warranty and 30-day free returns. The Base IWB Glock 17 holster is designed for EDC and all-day comfort. It can be worn cross draw, appendix, strong side, or all the way to small of back. Our concealed carry Glock 17 holster fully protects the trigger and mag release for ultimate safety. If you have a Glock 17 with optics or red dot, we have you covered with our optics ready cut. The optics cut is compatible with or without optics, so if you plan to add one later, getting the optics cut now is a good idea.
