We have P80 Jigs only for the following models:

The 80% jig makes finishing your semi-finished frame simple.

The frame guides were to sand, snip, and dermal the rail and locking block “tabs”.

The P80 jig also has a drilling template (drill bits included) to ensure your lower parts kit is secure.

The sizing is slightly different based upon which P80 model you are building, i.e., full size, compact, sub-compact, or single stack; however, the jig finishing process is essentially the same.

If you are looking for how best to use the Polymer 80 Jig or which one to buy online, keep reading!

The Polymer 80 or “ghost gun” laws have recently been changed to no longer allow shipping of the P80 frame and jig by the same company.

Oddly enough, the frame and jig are still 100% legal to own.

Polymer 80 Jig Overview

Every Polymer 80 jig only includes everything you need to finish your 80% Glock pistol build.

What’s Included with the Polymer 80 jig:

• Red Polymer 80 Jig for the PF9* P80-*-JIG
• Locking Block Rail System Pin, 3mm diameter x 25mm long MSC-PFP-PIN-3MM
• Trigger Mechanism Housing Pin, 3mm diameter x 25mm long pins MSC-PFP-PIN-3MM
• M3 Drill Bit – For drilling the Trigger Mechanism Housing pin hole MKI-Drill-M3
• M4 Drill Bit – For drilling the trigger pin hole MKI-Drill-M4

Checking out a few Youtube videos and reading the Polymer 80 “finishing guide” & P80 Colors online can help ensure first-time perfect build quality.

Building 80% firearms require patience and studying but can be accomplished by nearly anyone with a brain.

Rail Guides

The rail guides or tab cutouts show Polymer 80 builders which part of the polymer frame to remove to install the rear rails and locking block.

While you can’t go full out with a Dremel to finish the frame (you will remove too much polymer once close to the jig), you can start with the Dremel tool.

Having built a handful of Polymer 80s myself, I have found that there is a trick to make removing the P80 tabs easy:

1. Purchase “flat” end snips and cut the tabs down as close to flush with the frame and jig as possible.
2. Sand down with 60 or 80-grit sandpaper.
3. Continue raising the grit of the sandpaper after removing the jig until you are over 1500 grit and the tab removal area is smooth.
4. You can finish with a bit of wet 2000 grit sandpaper to make your Polymer 80 frame look factory-finished.

Drilling Holes

Drilling the holes for the Polymer 80 sounds like a “no brainer” task.

This would be an incorrect assumption.

Don’t skimp on this step. While possibly the shortest part of building a P80, if you drill these holes just slightly off center or unaligned, everything else will be 10x more difficult.

Take your time and build your P80 frame properly the first time around.

A few tips for drilling holes correctly to keep in mind:

1. Ensure your frame is seated and locked fully within the Polymer 80 jig.
2. Before drilling, place the jig on a flat, even, hard surface.
3. Do not use a drill press; the bit can sometimes be just slightly unaligned and will lead to an unusable frame.
4. Use a hand drill only for the Polymer 80 jig. While it may seem counterintuitive, it is suggested by the manufacturer and just works.

P80 Jig Models

The Polymer 80 jigs are similar to the method used to complete your build.

The differences are mainly in the overall frame size template for the jig or altered pinhole placement.

The placement of the pin holes varies between models, but the tab removal process is always the same.

Let’s dive into the differences in the jigs between the various Polymer 80 versions.

PF940C Jig Glock 19

The PF940C or the Glock 19 Polymer 80 jig only is the standard red jig with the tab removal template, locking block area, and drill bits for the pin holes.

The part number for the PF940C jig is P80-PG940C-JIG.

For the Compact version of the Polymer 80, you will need to drill the M3, and M4 labeled pin holes.

PF940v2 Jig Glock 17

The PF940v2 or the Glock 17 Polymer 80 jig is the standard full-size red jig with the tab removal template, locking block area, and drill bits for the pin holes.

The part number for the PF940v2 jig is P80-PG940v2-JIG.

For the full-size version of the Polymer 80, you will need to drill the M3, and M4 labeled pin holes.

This is overall the same as the compact G19 build but slightly larger.

PF940SC Jig Glock 26

The PF940SC or the Glock 26 Polymer 80 jig is the smaller sub-compact red jig with the tab removal template, locking block area, and drill bits for the pin holes.

The part number for the PF940SC jig is P80-PG940SC-JIG.

For the Sub Compact version of the Polymer 80, you will need to drill only the M4 labeled pin holes.

The G26 or sub-compact p80 does not require the third locking block pin or pinhole.

PF94SS Jig Glock 43

The PF94SS or the Glock 43 Polymer 80 jig is the single stack red jig with the tab removal template, locking block area, and drill bits for the pin holes.

The part number for the PF94SS jig is P80-PG94SS-JIG.

For the Single Stack version of the Polymer 80, you will need to drill the M3, and M4 labeled pin holes.

If you are familiar with the Glock models, this frame is the single stack magazine version which is relatively slimmer than the average Glock.

Shop Polymer 80 (Glock) Jigs

Recent laws have made shipping both Polymer 80 jigs and frames illegal.

This rule may seem arbitrary, but it does make it a PITA for 80% of builders and distributors to enjoy the 80% building hobby.

You must buy the jig and frame separately in our 3D Gun Builder store.

Conclusion

The Polymer 80 jig is what makes 80% building possible and such an accessible hobby for DIY gun builders.

While the laws are constantly changing, patience is required to build a P80.

If you use the jig correctly, slow down and read directions thoroughly. You can have yourself a factory-quality handgun or so-called “ghost gun” over a weekend of building.
