Upgrading your GLOCK® or Polymer80 is easy with a complete slide kit. Want to finish your Polymer80 frame without trying to pick out the right parts for your slide?

Each complete slide kit includes every part needed to make your pistol functional. Pair your slide kit with a set of GLOCK sights, and don't forget an RMSc- or RMR-type red dot if you're grabbing one of our optic-cut kits!

Complete GLOCK Slide Compatibility

We Cannot Ship Slide Kits to All 50 States

Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
