Why the Polymer80 P80-JIG-RL556v3 Jig Kit Makes Sense for Your Build
Having handled more jigs and 80% frames than I can count, I can tell you this isn’t just a piece of plastic. It’s the bridge between a raw polymer blank and a functional firearm. For the budget-conscious builder—maybe someone putting together a dedicated truck gun or a backup piece for their concealed carry lifestyle—this jig eliminates guesswork. It’s designed for the RL556v3 frame, which is a popular platform for a reason. The alignment is consistent, the drill guide holes are true, and it holds everything steady while you work. You’re not paying for bells and whistles; you’re paying for a tool that does one job very well, letting you focus on the craftsmanship of your build.

How Does This Polymer80 Kit Stack Up?
Let’s be real: not all jigs are created equal. I’ve seen the cheap imports that flex under pressure and the ultra-premium aluminum ones that cost more than some complete pistols. Here’s how this P80 kit finds its place.
| Feature | Polymer80 P80-JIG-RL556v3 | Generic Import Jig (~$65) | Premium CNC Aluminum Jig (~$250+) |
|---|---|---|---|
| Material | High-strength polymer | Basic, often brittle plastic | 6061 Aluminum |
| Quality & Fit | Precision-molded for specific RL556v3 frame | Loose tolerances, generic fit | Machined to exacting tolerances |
| Compatibility | Designed solely for Polymer80 RL556v3 | “One-size-fits-most” claims | Often brand/model specific |
| Shipping & Availability | In stock, ships same-day from ND | Long lead times from overseas | Frequent backorders |
| Lifespan/Durability | Designed for multiple uses, holds up well | May crack or warp after 1-2 uses | Effectively lifetime durability |
| Price | $50.99 | ~$65 – $80 | $250+ |
The takeaway? You’re getting OEM quality from Polymer80 at a price that undercuts generic imports. It’s the sensible middle ground. You won’t get the heft of an aluminum jig, but for most builders completing a few frames, this polymer jig is more than capable.
What You’ll Like (And What You Should Know)
Pros:
- ✅ OEM Fit & Function: Made by Polymer80 for their RL556v3 frame, so alignment is spot-on.
- ✅ Clear Instructions: Takes the mystery out of the process, great for first-time builders.
- ✅ Cost-Effective: At just over fifty bucks, it’s a minor investment compared to the total build cost.
- ✅ Reusable: Built sturdily enough to handle a few frames if you decide to build another.
- ✅ All Hardware Included: You get the pins and bits you need to start drilling right away.
Cons:
- ❌ Material Limitation: It’s polymer. If you’re a shop planning to run dozens of frames through it, consider a metal option. For the occasional builder, it’s fine.
- ❌ Single-Use Design (for most): Most folks buy one for their one build. If you’re a frequent builder, the per-use cost of a premium jig might make more sense long-term.
Who Should (And Shouldn’t) Buy This Jig Kit
Buy the Polymer80 P80-JIG-RL556v3 Jig Kit if:
- You’re building your first Polymer80 RL556v3 9mm pistol and want the correct, factory-specified tooling.
- You value a straightforward process with included instructions over figuring it out as you go.
- You’re a hobbyist on a budget who wants a reliable tool without the premium metal price tag.
- You appreciate having all the necessary hardware in one box, ready to go.
Skip this jig kit and look at alternatives if:
- You’re a commercial builder or plan to complete a very high volume of frames—a metal jig is a better investment. (See our gunsmithing tools for heavy-duty options.)
- You need a jig for a different model frame (like a PF940 series). (Check our full Polymer80 category for the right match.)
- You already own a universal or multi-model jig you’re happy with.

Frequently Asked Questions
What tools do I need besides this jig kit?
You’ll need a drill press or a very steady hand with a power drill, a vise to securely hold the jig, and the appropriate drill bits (which are typically included). A set of files or a milling tool for the recoil spring channel is also necessary for the frame completion.
Is this jig reusable for multiple builds?
Yes, it’s designed to be used more than once. The polymer construction is durable enough for several builds if you’re careful. However, for high-volume use, the wear on the drill guide holes over time may affect precision.
Does this work with any 9mm slide and parts kit?
This jig is specifically for completing the Polymer80 RL556v3 frame. Once the frame is finished, it should accept standard Glock-compatible 9mm slides and internal parts kits designed for the large-frame (Glock 17 size) platform. Always verify parts compatibility.
Is this a firearm? Do I need an FFL to purchase it?
No. The Polymer80 P80-JIG-RL556v3 Jig Kit is a tool, not a firearm or firearm component. It can be shipped directly to your door without involving a Federal Firearms License (FFL) holder.

I don’t write reviews often but Imbertsmithersarms deserves one. The Polymer80 P80-JIG-RL556v3 Jig Kit – 9mm is exactly what I was looking for. Good build quality, snug fit on my G22, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.

Decent product for the price. Not the absolute best quality I’ve seen but it works well on my Glock 17. Would buy again if the price stays where it is.
