Brownells Blank Slides for Glock® pistols come with the exterior left smooth and featureless so you can customize it exactly the way you want it. Add cocking serrations, an optic mounting slot, and cosmetic flourishes to make it entirely your own. (Yes, you will need to bring some machining skills to the table!)
Inside, the dimensions fully machined to factory dimensions, so your Brownells Blank Slide for Glock comes ready to fit a factory-spec frame and accept Gen 1-4 factory and aftermarket barrels and parts.
