Holster Molding Spacers and Blocking Plates

Shop holster molding spacers and blocking plates for building the trigger cavity and slide clearance into the mold before you heat and press the sheet. Choose from a Glock trigger spacer, a universal slide spacer and a universal slide release blocking plate, each made from steel in 0.10 or 0.125 inch thickness.

Trigger guard retention starts with the 0.125 inch (1/8 inch) Glock trigger spacer, which forms a clean, uniform retention area during molding so the holster holds the gun as intended. The 0.10 inch universal slide spacer does the same job along the slide, keeping spacing consistent from build to build.

The third jig, a 0.125 inch universal slide release block, closes off the slide release area for consistent retention and fit. Because the slide spacer and slide release block are universal, they move from one gun model to the next, while the trigger spacer is made for Glock holsters in thermoform plastic or leather. All three are USA-made steel, and each is sold as a 1-pack.

These spacers sit in molding preparation alongside retention plates, light widgets and sight dowels for the rest of the gun setup. If you mold for makes beyond Glock and want a hand planning trigger and slide spacing, our contact page reaches the shop directly.
