It appears Polymer80 is set to release a new 80% Glock compatible pistol frame at the 2018 SHOT Show. Called the PF940SC, the new unfinished frame is designed to be compatible with the sub-compact sized Glock pistols like the G26 and G27.
Polymer80 offers a number of 80% receivers that allow you to complete various machining and assembly operations to turn them into working firearms. This allows the hobbyist shooter to literally build their own gun.
Before now, the company offered only two sizes of Glock compatible 80% frames – one for full sized guns and another for the compact (Glock 19 style) frame. The new PF940SC would allow shooters to build a complete set of Glock compatible pistols.
The 80% frames are not copies of the Glock frame. Rather, they are new designs that are compatible with standard Glock parts. As a builder, you can simply order OEM parts kits and build your own pistol with this frame once you complete the needed machining on the frame.
The new frame uses reinforced polymer for a combination of strength and modest weight. A jig is included along with the tooling needed to machine the frame. Polymer80 opted to use a Picatinny-type accessory rail to allow the use of a light or laser when completed.
A stainless steel locking block with front rails and a drop-in rear stainless steel rail module are used. This is similar to the design used on the existing compact frames, and a significant improvement over the original full size frames. The original full size frame uses polymer rear rails that have to be milled, filed and hand fitted. It works, but it does take a lot of time to perfect.
Polymer80 anticipates a retail price of $149.99 when they come to market. This is in line with the company’s other Glock compatible frames.
If you’ve never built your own firearm using an 80% lower or frame, you might be surprised at how easy it is. It requires time and tools, but can be done as a Saturday project. Many guns – from AR-style rifles to 1911 compatible pistols – are made by hobbyists, and are completely legal under federal law.

It will be shipped right to your door without any need for the ridiculous fees associated with gun transfers.
