Polymer 80 Glock Frame Kit. MAD is pleased to offer the PF940C 80% Compact Pistol Frame by Polymer80. Offering compatibility with Glock® 19/23 Gen3 components, the PF940C is an industry first. Customers can choose between two different grip styles: the standard grip texture or ReadyMod grip providing a blank canvas for customization. Features like the extended beaver tail, double undercut trigger guard, and a thumb ledge considerably enhance the ergonomics allowing for an effective grip and improved recoil mitigation. The grip angle is also similar to a 1911. So if you haven’t switched to a Glock because of the grip angle that causes the firearm to point high, well, here is your solution.
