Talon Grips are textured, stick-on gun grips that help you get a secure hold on your firearm improving performance, safety, and confidence so you maintain control. Installation is quick and easy. The granulate grips (sandpaper gun grips) are more aggressive and best suited for open carry. This model is compatible with Glock 26,27,28,33,39 Gen with large backstrap. It will also fit both the large and the large beavertail backstrap.
