The Polymer 80 PF940C Custom Glock 19 frame comes with all the bits and parts needed to complete the frame.
What’s Included:
- 80% Frame
- Jig for milling and drilling
- 2x Drill bits
- 1X End Mill Bit
- Stainless Steel Front and Rear Rails
- All the pins needed
There are only 4 operations that need to be completed on the Polymer 80 PF940C lower receiver.
- Decking the front rails.
- Decking the rear rails.
- Milling the Barrel/ guide rod seat.
- Drilling the pin holes
The Official Polymer 80 Instructions state that we should mill the front and rear rail sections, and barrel seat
using the provided barrel seat using the provided end mill bit and a drill press.
Then drill the pin holes using a hand drill and the provided drill bits.
You can find the Official Polymer 80 PF940C Instructions Here.
However, we’re going to do things a little bit different.
Instead of using a drill press and XY Vise, we’re going to use the following:
- Large Hand Files
- Small Hand Files
- 400 Grit Sandpaper
- 600 Grit Sandpaper,
- 2000 Grit Sandpaper
- WD-40
- Hand Drill
- Bench Vise
- Soft Jaws
- Dremel 4000
- Real Avid Smart Bench Block
- Wheeler Hammer & Punch Set
Although this method takes a little longer to complete the PF940C frame; you will be amazed by the results.
Let’s Get To Work
Step 1:
Place thePolymer80 PF940C Frame into the Jig.
Step 2:
With the soft jaws installed on the bench vise.
Place the Polymer80 PF940C jig into the vise, with the rail sections facing toward the ceiling.
Caution!
Be careful not clamp the vise down too tight, as this can causing the jog to become deformed.
Step 3:
Take a medium grit large file and start filing the front rails.
Be care as not to file and of the red portions of the jig.
Once you have the front rails flush with the jig, go ahead a stop.
We will smooth everything out later.
Step 4:
Now take a narrower file and repeat the same process on the rear rail section.
Step 5:
Now let’s file down the barrel seat.
Be careful as to only mill the portion indicated by the red marking in the Official Polymer 80 PF940C Instructions.
Make sure that this part is done as smoothly as you can make it.
A poor job on this part will cause the slide not to track smoothly.
Step 6:
Caution!
Do not drill all the way through the jig!
Instead drill the holes on one side of the jig, then move to the opposite side to finish.
Now let’s drill the pin holes.
Included in the Polymer 80 PF940C kit are 2 drill bits.
One small bit and one larger bit.
Using a hand drill use the small bit to drill the small holes.
Then use the larger bit to drill the larger hole on each side of the jig.
Congratulations!
