Pearce Grip Frame Insert for Glock 20SF & 21SF
The Pearce Grip Frame Insert for the Glock 20SF and 21SF is a precision-fit accessory designed to seal the bottom rear cavity of your Short Frame pistol, keeping dust, debris, and moisture out of the frame while giving the grip a clean, finished appearance.
- Friction-fit design secures snugly in the Glock 20SF and 21SF frame cavity
- Constructed from high-impact polymer for long-lasting durability and reliability
- Keeps dust, debris, and grime out of the grip frame interior
- Provides a clean, factory-finished look to the underside of the grip
- Lightweight and low-profile — adds no bulk or weight to your pistol
- Compatible exclusively with Short Frame models; does not fit Gen 4 or standard frames
Who This Is For
This grip frame insert is ideal for Glock 20SF and 21SF owners who want a tidy, well-protected firearm without the open cavity at the base of the grip. Whether you carry your pistol in the field, store it long-term, or simply prefer a polished look, this insert is a simple and affordable upgrade. It is especially useful for shooters in dusty or outdoor environments where debris intrusion into the frame is a concern.

Frequently Asked Questions
Will this insert fit my standard Glock 20 or Glock 21 (non-SF)?
No. This frame insert is designed specifically for the Short Frame (SF) variants of the Glock 20 and 21. The cavity dimensions on the standard G20 and G21 frames differ, so this insert will not fit correctly. It is also not compatible with Generation 4 frames. Always verify your pistol's model designation before purchasing.
Does this insert affect the function or reliability of my pistol?
No — the Pearce Grip Frame Insert is a passive accessory that simply fills the open cavity at the bottom rear of the grip frame. It does not interact with any internal components, the trigger mechanism, or the magazine. It seats via friction fit and can be removed without tools if needed.
Is this product made or approved by Glock?
No. This product is manufactured by Pearce Grip and is not manufactured, authorized, endorsed, or warranted by GLOCK. Glock does not warrant or represent that aftermarket accessories are compatible with their pistols. That said, Pearce Grip is a well-established aftermarket manufacturer with a long track record of producing quality, drop-fit Glock accessories.
