Build a custom GLOCK®-compatible slide with one convenient kit!
Ready to finish that Polymer80 frame you fabricated? Want an upgraded slide that looks great and shoots even better? Check out our GLOCK® complete slide kits. Each kit includes OEM or better components, plus custom slides with optional red dot optic cuts and threaded carbon or stainless barrels, ready for a compensator or can.
All kit slides are cut for factory GLOCK® iron sights, sold separately. Grabbing an optic-cut and drilled slide? Pair it with a micro red dot (available here).
Our custom slide kits are compatible with Polymer80 frames and Gen 1 to Gen 3 factory GLOCK® frames. A Gen 3 slide will not fit a current (Gen 5) GLOCK® frame. We've tested this intercompatibility and found clearance issues when attempting to seat a Gen 3 slide on a Gen 5 GLOCK® 19 frame.

Assembling your custom GLOCK slide is easy. You only need a few, simple tools: A channel liner install tool, punch set, and small gunsmith hammer (tools available here). Assembly takes as little as 15 minutes and is easily accomplished by first-timers.
Use our written slide assembly instructions, or watch our how-to video!
