Why This P80 Kit Makes Sense for Your Build
When I talk to hunters and shooters up here, the conversation usually isn’t about having the fanciest gun on the range. It’s about having a tool that works when you need it, without breaking the bank. That’s the mindset behind this P80 Thr/Flu Brl N/Sght kit. It’s not a luxury item; it’s a practical solution. You’re getting the key components—threaded barrel, front and rear sights, and a 15-round magazine—in one package. This means less time hunting down individual parts from different suppliers and more time getting your build range-ready. For the concealed carry lifestyle or a truck gun, starting with a matched kit like this removes a lot of the guesswork about compatibility.

How It Stacks Up: P80 Kit vs. Other Options
| Feature | P80 Thr/Flu Brl N/Sght Kit (~$569) | Budget Aftermarket Kit (~$60-$80) | Premium Branded Kit (~$250+) |
|---|---|---|---|
| Material | Steel slide, carbon steel barrel | Often alloy or lower-grade steel | Stainless or chromoly steel |

The Pros and Cons, Straight Talk
Pros:
- ✅ Complete Kit: Gets you the major upper components in one purchase—slide, barrel, sights, guide rod, and magazine.
- ✅ Threaded Barrel Included: Ready for a compensator or suppressor (where legal), adding value over non-threaded options.
- ✅ P80-Specific Design: Engineered to work with Polymer80 frames, reducing compatibility headaches.
- ✅ Functional Sights: Comes with front and rear sights installed, so you can at least get zeroed and shooting.
- ✅ Good Value for a Complete Upper: When priced against buying each quality part separately, the bundle makes budget sense.
Cons:
- ❌ Not a Complete Firearm: You must pair it with a Polymer80 lower frame, parts kit, and complete the build yourself. It’s a project.
- ❌ Sights are Basic: They’re serviceable three-dot sights, but serious shooters will likely want to upgrade to night sights or a optic-ready system later. Check out our sights & optics when you’re ready.
- ❌ Requires Assembly & Tools: This isn’t a plug-and-play item. You’ll need punches, a vise, files, and some mechanical aptitude.
Who Should (and Shouldn’t) Buy This P80 Kit
Buy it if:
- You already have a Polymer80 PF940v2 or PF940C frame and need the upper components.
- You’re looking for a budget-conscious but reliable starting point for a 9mm build.
- You want a threaded barrel included without a significant price jump.
- You enjoy the process of building and customizing your own firearm.
- You need a spare/backup upper assembly for an existing P80 build.
Skip it if:
- You want a complete, ready-to-shoot firearm right out of the box. (Look at our complete handguns instead).
- You have no interest in or experience with firearm assembly. The learning curve is real.
- You’re building for extreme precision competition; you’ll want higher-tier components.
- You need a kit for a frame other than the P80 PF940v2/PF940C (Glock 17/19 size).
Common Questions & Concerns
“Is this kit legal in my state?”
Firearm laws are local and change often. It is your responsibility to know and comply with all federal, state, and local laws regarding firearm ownership, build kits, magazine capacity (this includes a 15-rd mag), and threaded barrels before purchasing. We ship in full compliance with federal law to the address on your FFL’s license.
“What else do I need to finish the build?”
You’ll need a Polymer80 PF940v2 or PF940C frame (the lower), a lower parts kit (LPK) with all fire control components, a magazine, and the appropriate tools. We sell most of these items separately.
“How’s the reliability?”
Based on handling and customer feedback, these kits provide reliable performance for recreational shooting and training when properly assembled on a well-finished P80 frame. As with any built firearm, a proper break-in period (a few hundred rounds) is recommended to ensure smooth operation.
Frequently Asked Questions
What does “Thr/Flu Brl N/Sght” mean?
It’s an abbreviation for the kit contents: Threaded Fluted Barrel with Night Sights (or sometimes listed as No Sights, but this kit includes basic three-dot sights). It describes the key features of the slide assembly.
Is the barrel truly threaded?
Yes, the included barrel is threaded, typically with 1/2×28 threads, which is the common pitch for 9mm accessories like compensators or thread protectors. A thread protector may or may not be included; check the product images or description for the latest details.
Does this work with a Glock 19 Gen 3 frame?
No. This kit is designed specifically for the Polymer80 PF940v2 or PF940C frames, which are based on the Glock 17/19 Gen 3 footprint but are not identical to OEM Glock frames. It will not fit directly on a factory Glock frame without modification, which is not recommended.
What kind of accuracy can I expect?
With the included barrel and proper assembly, you can expect combat-accurate performance suitable for self-defense, training, and recreational shooting at typical handgun distances (7-25 yards). It is not marketed as a match-grade precision barrel.
Is the slide optics-ready?
This specific kit comes with a slide that is cut for and includes iron sights. It is not pre-milled for a red dot optic (RMR, Doctor, etc.). If you want an optics-ready slide, you would need to purchase that separately or have this slide milled by a gunsmith.
Where can I buy P80 build kits online?
You can purchase the P80 Thr/Flu Brl N/Sght 15rd – 9mm and other build components right here at Imbertsmithersarms (imbertsmithersarms.com). We’re based in Grand Forks, ND, and ship quickly and discreetly.
Do you ship to my door?
No. Due to federal regulations, this kit contains a firearm component (the slide) and must be shipped to a licensed Federal Firearms License (FFL) holder of your choice for transfer, just like a complete firearm. You will need to arrange the transfer with your local FFL dealer.

I’ve been shooting for 10 years and I’m picky about where I buy accessories online. Imbertsmithersarms earned my business. The P80 Thr/Flu Brl N/Sght 15rd – 9mm arrived in 3 days, packaged well, and fit my G17 Gen4 without any modification. I put 417 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.

Bought this as part of a larger build project. Imbertsmithersarms had the best price by a decent margin and shipping was fast. The P80 Thr/Flu Brl N/Sght 15rd – 9mm itself is well-made — No wobble at all. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
