Why Choose the Polymer80 PF940SC™ Frame?
After over a decade in this business, I’ve seen a lot of frames come through our warehouse. What makes the PF940SC stand out isn’t just the Polymer80 name—it’s the thoughtful engineering. This is the compact ‘SC’ model, designed for a balance of concealability and shootability. It’s built for the guy who wants a project that results in a serious, everyday-use firearm, not just a range toy. The jig system is straightforward, and the polymer is tough. For the price, you’re getting a platform that, when paired with quality parts, will run as reliably as anything off the shelf, but it’ll be yours—built to your grip and your specs. It’s the cornerstone of a truly personalized sidearm.

How Does the Polymer80 PF940SC Stack Up?
When you’re shopping for an 80% frame, you generally have three tiers to consider. Here’s how the PF940SC holds its own against the competition.
| Feature | Polymer80 PF940SC | Budget Import Frame (~$60-80) | Premium Machined Aluminum Frame (~$250+) |
|---|---|---|---|
| Material | Reinforced Polymer | Basic Polymer | 7075-T6 Aluminum |
| Quality | High, consistent molding, good fit | Variable, often poor mold lines & flex | Exceptional, CNC-machined precision |
| Compatibility | Excellent with Gen 3 parts | Hit-or-miss, often requires fitting | Excellent, but often for specific slides |
| Shipping | Fast, from US-based retailers like us | Slow, international shipping common | Fast, from niche manufacturers |
| Lifespan/Durability | Proven long-term durability for polymer | Questionable long-term wear resistance | Maximum durability and rigidity |
| Price | $160.99 – Balanced value | Cheapest upfront cost | Significant investment |
The PF940SC sits in the sweet spot. It’s not the cheapest, but you avoid the headaches of an unknown import. It’s not a premium metal frame, but for a concealed carry or hunting sidearm, the polymer weight savings and proven track record make it a smarter choice for most folks.
Pros and Cons of the PF940SC Frame
Pros:
- ✅ Proven Platform: Based on the ubiquitous Gen 3 Glock pattern, parts and holsters are everywhere.
- ✅ Excellent Value: For around $160, you get a high-quality US-made foundation for a custom pistol.
- ✅ Ergonomic Design: The frame has a more natural grip angle than some factory options, which many shooters prefer.
- ✅ Includes Jig: Polymer80 includes a quality machining jig, making the completion process much more accessible.
- ✅ Compact & Concealable: The ‘SC’ size is ideal for a concealed carry build or a handy woods gun.
Cons:
- ❌ Requires Work & Tools: This is not a drop-in part. You need a drill press or hand drill, files, and some mechanical aptitude. If that’s not your thing, check out our complete pistols.
- ❌ Polymer Feel: Some shooters simply prefer the heft and solidity of a metal frame. If that’s you, you might want to browse our metal frame options.
- ❌ Legal Responsibility: The builder is responsible for understanding and complying with all federal, state, and local laws regarding the manufacture and possession of firearms.
Who Should (and Shouldn’t) Buy This Frame
Buy the Polymer80 PF940SC if:
- You’re an experienced hobbyist who enjoys building and customizing your own gear.
- You want a compact, reliable 9mm for concealed carry without the premium price tag of a custom shop gun.
- You value having a personalized firearm that isn’t identical to every other one on the range.
- You understand the tools, process, and legal requirements involved in completing an 80% frame.
Skip the Polymer80 PF940SC if:
- You’re looking for a ready-to-shoot firearm right out of the box. (We have plenty of those here.)
- You lack the tools, workspace, or confidence to complete the machining process safely and accurately.
- Your local laws restrict the possession or manufacture of unserialized firearms.
- You absolutely require a metal-frame pistol for perceived durability or recoil management.
Have Concerns? Let’s Address Them.
Is this legal for me to buy and build?
At the federal level, for an individual building a firearm for personal use (not for sale or distribution), completing an 80% frame into a functional firearm is generally legal. However, you must be legally eligible to possess a firearm. Several states and localities have enacted their own laws restricting or banning such items. It is your responsibility to know the laws in your city, county, and state before purchasing.
How difficult is the build process?
With the included jig, basic tools (a drill press is highly recommended over a hand drill), and patience, it’s a manageable project for someone with moderate DIY skills. There are countless detailed video guides. The most common issue is rushing—take your time with the drilling and milling.
Will my aftermarket Glock parts fit?
For the most part, yes. The PF940SC is designed for Gen 3 Glock 26/27/33 parts. Some aftermarket parts, especially triggers and connectors, may require minor fitting, which is typical even with factory frames. Stick with reputable parts kits for the smoothest build.
Frequently Asked Questions
What tools do I need to complete this Polymer80 PF940SC frame?
At a minimum, you will need a drill (a drill press is strongly recommended for precision), the correct size drill bits (typically included with a jig kit or available separately), a hand router or Dremel tool with milling bits, and various hand files and sandpaper for finishing. Polymer80 often sells tool kits designed for their frames.
Is the jig included with the Polymer80 PF940SC frame?
Yes, the Polymer80 PF940SC frame is sold with the necessary machining jig. This jig is essential for correctly drilling the pin holes and guiding the milling of the fire control group pocket. Always use the jig provided with your specific frame.
What parts kit do I need for this frame?
You will need a parts kit compatible with a Gen 3 Glock 26 (for 9mm). This includes a lower parts kit (LPK) with all pins, springs, trigger assembly, slide lock, etc., and a locking block specific to the PF940SC frame. The slide, barrel, and recoil spring assembly are purchased separately.
Can I build this into a .40 S&W or .357 SIG pistol?
Yes. The PF940SC frame is designed to be compatible with Gen 3 Glock 27 (.40 S&W) and Glock 33 (.357 SIG) components as well. You would simply need a slide, barrel, and magazines chambered in your chosen caliber, along with the corresponding lower parts kit.
How does the grip compare to a factory Glock?
<
The Polymer80 frame has a different grip angle (more akin to a 1911) and texture than a factory Glock. Many shooters find it more ergonomic and less prone to muzzle rise. The frame also lacks the finger grooves found on later Gen Glocks, offering a cleaner grip profile.

Bought this as part of a larger build project. Imbertsmithersarms had the best price by a decent margin and shipping was fast. The Polymer80 PF940SC™ 80% Pistol Frame ONLY – 9mm itself is well-made — Better than expected at this price. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
