The Bluegun® Holster Molding Prop for the Glock 21 SF with Picatinny Rail is a rugged, full-size tool built for craftsman-grade holster making. Designed to match the exact dimensions of the Glock 21 SF, including its integrated Picatinny rail, this molding prop allows for precision-formed holsters without ever risking wear on your firearm.
Crafted from highly durable polymer and finished in matte blue, this mold stands up to repeated use and heat exposure during thermoforming. Its accurate replication of size and shape ensures each holster you form delivers a professional fit and reliable retention. Whether you’re molding for everyday carry, duty, or tactical applications, this prop delivers consistent performance and repeatable results in your workshop.
For best results, use a dowel rod or similar insert to form proper sight channel clearance during the molding process.
