Let’s start off this article by clearing up any confusion that may arise from the term P80 Rails and have everyone on the same page.
Before you get all excited and start daydreaming about slapping on a rail to your P80 build and adding insane tactical gadgets that will have people thinking Robo Cop gave you the pistol as a birthday present, itโs not that type of rail.
We are going to discuss the various P80 rail systems that form part of the internal components within the frame, specifically the Locking Block Rail Module (LBRS) and Rear Rail Module (RRM) plus we will throw in a little bonus towards the end of the article for those dedicated P80 builders.
P80 Rails Installation Re-Cap
For those of you that are comfortable with the installation of the rails into the frame, you can keep scrolling past this section.
For the Polymer 80 builders that may still need a little recap, we are going to briefly go over the installation process and highlight a few key points to take note of during the build.
- Suppose the most obvious thing to point out is to ensure you have the correct P80 frame/kit for the Glock you want to build.
- PF940v2 for a full-size Glock 17/22/33/34/35
- PF940CV1 for a compact Glock 19/23/32
- PF940SC for a Glock 26
- PF9SS for the single stack G43 series
- The standard kit will contain the plastic finishing jig, frame, Rear Rail Module (RRM), Locking Block Rail Module (LBRS), pins, and drill bits. Parts may vary with different molds but more on that later.
- Milling of the frame: With the frame in the finishing jig, the front and rear segments will need to get milled with the provided drill bit, once completed the milling out of the barrel block is to be done.
- File off and sand smooth the areas on the frame that were milled with the drill bit. Continue until those areas are flush with the body of the frame.
- Using the correct drill bit, drill through the 6 holes (3 on each side) of the finishing jig and into the frame.
- Insert the magazine release and slide lock spring (which varies between the full-size and compact sizes) and connect with the slide lock.
- Once those components are in, the Locking Block Rail System (LRBS) can be inserted with gentle taps from a non-metal hammer. Using a punch insert the accompanying pin.
- Push the Rear Rail Module (RRM) into the rear segment of the frame, but do not add the accompanying pin just yet.
- Complete the full trigger assembly and insert it into the frame finishing it off with the trigger pin.
- Take the smaller metal pin along with the slide stop lever and insert it so that the spring sits underneath and fits the smaller pin.
Ah if only it were that simple but for a recap and overview that is the process required for the correct installation of the rails.

Buy Polymer80 Rails Only?
So, to answer this question bluntly we are going to say โYesโ.
The main reason for this comes down to the warranty. Polymer80 supplies all the parts necessary and should something go wrong, you would be covered under warranty.
Now to add a little more context, we are going to add a โbutโฆโ after the answer because there are alternatives that may or may not be better than the P80 rails.
Metal Injection Molding vs Machined Forged Billet
To fully understand where our โbutโฆโ comes from we need to briefly explain the way in which these rails are manufactured.
Polymer80 and even Glock manufacture their rails through a process called Metal Injection Molding (MIM), which is great for producing small parts in mass.
Metal Injection Molding parts however are notorious for failing under stress and pressure over time, with the MIM grain structure wearing and exposing metal particles that are released into the surface.
Now when locking blocks are machined from a forged billet block of heat-treated stainless steel it results in better grain structure, more strength, a higher achievable surface, tighter tolerances, and most importantly everything is straight and parallel.

FAQs
The more experienced builders may use a dremmel, however, in the wrong hands, it can cause more damage than good. Others have suggested using 1200-2000 grit sandpaper with a little gun oil. Remember you only looking to smooth off the rails, so only polish if necessary.
Yes, you can. Although Polymer80 does not exclusively offer the purchasing of individual rails, there are other manufacturers out there that do.
Conclusion
What you need to know about the rails on your Polymer80 build is to ensure you have the correct frame with corresponding rails.
As much as we would all love to have all the pieces slide in smoothly, that isnโt the case so a little polishing, persuading, and patience is necessary when installing the rails.
Now, if you have read this far, it’s time to be rewarded and here it is. We sell the relevant rails right here on this page and offer everything you need for the build, so no need to look any further.
