The Polyflex Slide Plate is a black rear slide cover plate from Strike Industries (brand part no. SI-POLYFLEX-GSP), sized to fit Glock 17 and 19 pistols. It replaces the factory rear slide cover plate that caps the back of the slide over the striker channel, using Strike Industries’ Polyflex composite material rather than the stamped-steel factory part. It’s a simple, affordable swap for Glock 17/19 owners looking to lighten or personalize the rear of the slide.
