Expert review
About this product
What is the PF940SC - Polymer 80? It is a subcompact 80% pistol frame designed for Glock 26/27/33 builds, requiring user completion for functional use. This frame uses high-impact polymer construction and includes pre-molded rail sections for slide compatibility. Production has been temporarily halted, making this a final opportunity to acquire this specific model.
What is the PF940SC - Polymer 80 used for?
The PF940SC is used for building custom subcompact pistols chambered in 9mm, .40 S&W, or .357 SIG. It requires drilling three pin holes and removing three polymer tabs to complete the frame. This process typically takes 45-60 minutes with a hand drill and end mill bit.
How does the PF940SC - Polymer 80 compare to the Polymer80 PF940V2?
The PF940SC is better for concealed carry due to its shorter grip length, while the PF940V2 supports full-size Glock 17 magazines. The PF940SC measures 6.3 inches in overall length compared to the PF940V2's 7.9 inches. Both frames use identical polymer blends and require similar completion procedures.
What does it weigh and what are the dimensions?
The unfinished PF940SC weighs 8.2 ounces and measures 6.3 inches long, 4.8 inches tall, and 1.2 inches wide. Completed weight with slide and barrel averages 22 ounces. Rail spacing is 18.5mm between front and rear sections, matching standard Glock slide specifications.
Who is this NOT for?
This frame is not for beginners without proper tools or those in jurisdictions restricting unfinished frames. It requires a drill press or steady hand drill, end mill bit, and vise for proper completion. California residents should review more on state compliance guidelines before purchase.
What's in the box?
The box contains one unfinished PF940SC frame, one locking block, and one rear rail module. No jig, drill bits, or pins are included—these must be sourced separately. Compare to the see Polymer80 80% Lower Receiver and Jig Kit which includes completion tools.
Is the PF940SC - Polymer 80 worth it at $89?
At $89, it is worth it for builders seeking a subcompact platform with customization potential. Finished Glock 26 frames typically cost $200-$300 from OEM suppliers. This represents a 55-65% savings for those willing to complete the machining work themselves using techniques from the our drilling guide.

Frequently asked questions
- Is it compatible with Glock 26 slides?
- Yes, it accepts standard Glock 26 slides and barrels. Rail spacing matches OEM specifications at 18.5mm between front and rear sections. You may need to adjust slide stop tension using methods from our technical guide.
- Does it fit Glock 19 magazines?
- No, it only accepts Glock 26/27/33 magazines due to shorter grip design. Magazine well height is 4.8 inches compared to 5.4 inches on full-size frames. Use OEM or aftermarket 10-round magazines for reliable feeding.
- How long does shipping take?
- Shipping typically takes 3-5 business days within continental US. All orders ship via USPS Priority Mail with tracking. International shipments may require 10-15 days and additional customs documentation.
- Can I return it if it doesn't fit?
- No returns are accepted on 80% frames due to their nature. All sales are final once machining begins. Verify compatibility with your slide using caliper measurements before starting work.
- Does this work with Lone Wolf slides?
- Yes, it works with most aftermarket slides including Lone Wolf and Brownells. Some may require minor rail fitting with 400-grit sandpaper. Always test fit before final assembly.
