Gen 3 G20  Magwell Adapter for Glock 20 Gen 3 only (Fatback Type)

USE A 2mm Wrench to secure screw

Due to the G20 frame variances year to year it is recommended to use the SLR Glock 10mm Floor plate (Link Below)

Some frames will not allow easy mag retention in frame when using magwell. Frame to frame this can vary.

Our Glock 10mm Floor plates solve this issue.

-NOT For SF versions 

- 7075 Billet Aluminum

- Includes ultra low-profile billet attachment screw

- Made to fit each gen and model like a glove. No "one size fits all" like many out there

- Includes relief for Taran Tactical pin

- Will work with 10-round mags (for states with capacity restrictions)

- Will not work with back straps

Magwell screw only needs to be finger tight. Do Not Overtighten.

NOTE- install over front lip of grip before pushing rear into place.
