Polymer80 PF940 Series Milling Guide

Polymer80 PF940 Series Milling Guide

The Polymer 80 PF940C 80% frame will work with Generation 3 Glock parts.  You can either build it out to be a clone of the G19, G23, or G32 pattern. Caliber wise, you can choose between 9mm, .40 S&W, and the .357 SIG.  Additionally, if you choose to purchase a .22LR conversion slide, you can also build it out into a .22LR trainer so you can enjoy the same trigger pull of your carry gun while shooting the much cheaper .22LR round.

1.  Verify you are using a compatible frame.

a.  There is a difference between the generations of slides and frames. The generation 4 and 5 slides and parts will not work on this frame.

b.  While other frames such as the PF940SC and the PF940V2 may (with some coaxing) fit into the Polymer 80 jig that we offer, we do not offer code to support those frames.

2.  True T-slot Platform

a. We recommend you to follow the procedure in this video to properly set your t-slot platform, prior to milling pistol frames.

4.  Know Order of Operations

a.  The P80 cutting programs use the following operations to complete an 80% P80 940C frame: 

• Barrel guard and ribbing milling operation using an Onsrud ¼” End Mill
• Drill trigger pin hole using a #22 jobber Drill
• Drill RRM pin hole using a 3mm Drill

5.  Cutting Code

a.  The main P80 cutting program ‘p80 2019.03.14.dd’ will run all three operations and is located in Ghost Gunner/Cutting Code/Polymer80 Code/.

b.  If you’d like to run the second operation (drilling of the two pin holes), operation 2 of the cutting program can be found in the Additional Polymer80 Code folder.
