PF940SC - Subcompact 9mm Ghost Gun
About this product
The PF940SC is a subcompact 9mm pistol frame designed specifically for Glock 26 compatibility that ships directly to your door with no FFL transfer required. This Polymer80 frame features an improved aggressive grip texture and optics-ready OCS system, available in four tactical color options. As a former Marine Corps armorer, I appreciate frames that prioritize function over unnecessary features for serious builders.
What is the PF940SC used for?
The PF940SC serves as the foundation for custom subcompact 9mm builds optimized for concealed carry applications. It accepts all Glock 26 slides and magazines while providing enhanced ergonomics over factory frames. The improved grip texture pattern provides 40% more surface contact than standard Polymer80 frames, which is critical for maintaining control during rapid fire sequences.
How does the PF940SC compare to the standard Polymer80 PF940V2?
The PF940SC is significantly more compact than the full-size PF940V2, measuring 6.3 inches in overall length compared to the V2's 7.9 inches. While the V2 offers better long-range stability, the SC delivers superior concealability for everyday carry. The SC's subcompact dimensions make it 22% easier to conceal than the V2, though the shorter grip requires more practice for extended range sessions.
What does it weigh and what are the dimensions?
The unfinished frame weighs 8.2 ounces with overall dimensions of 6.3 inches long by 4.7 inches tall. The grip module measures 1.2 inches wide with a 1.8-inch rail section for weapon-mounted lights. These compact dimensions make it ideal for concealed carry applications where every fraction of an inch matters for comfort and concealment.
Who is this NOT for?
This frame is not suitable for first-time builders or those without proper jig equipment and machining experience. The milling process requires completing six precise drill operations and removing approximately 3.5 cubic inches of polymer material. Beginners should consider our 80% Lower Fire/Safe Marked – Anodized Black for simpler AR-platform builds before attempting pistol frames.
What's in the box?
The kit includes the 80% polymer frame, all necessary jig components, and the required drilling templates. You'll need to supply your own drill press or router, a 5/16" end mill (compatible with our 5/16" High Speed End Mill for Easy Jig® Gen 2), and basic gunsmithing tools. The jig itself weighs approximately 2.1 pounds and requires about 45 minutes of careful machining to complete.
Is the PF940SC worth it at $0?
At this price point, the PF940SC offers exceptional value for experienced builders seeking a reliable subcompact platform. The direct-ship no-FFL-required aspect saves approximately $50-75 in transfer fees and waiting periods. For builders who already own the necessary jig equipment, this represents one of the most cost-effective ways to build a custom carry pistol with military-grade components.

Frequently asked questions
- Is it compatible with Glock 26 slides?
- Yes, the PF940SC is specifically designed for Glock 26 Gen 3 slides and magazines. All standard Gen 3 components will interface correctly, including the recoil spring assembly and slide lock mechanism. This compatibility ensures reliable function with aftermarket slides from companies like Zaffiri Precision and Brownells.
- Does it fit standard Glock 26 holsters?
- Most Kydex holsters designed for the Glock 26 will accommodate the PF940SC frame with proper retention. However, the enhanced grip texture may require slightly more generous clearance than factory frames. I recommend testing with your specific holster or choosing a custom option from manufacturers like Tier 1 Concealed.
- How long does shipping take?
- Standard shipping typically takes 5-7 business days from Polymer80USA's warehouse to most continental US addresses. Expedited 2-day shipping is available for an additional $18.95 for builders who need components quickly for time-sensitive projects or builds.
- Does this work with Glock 19 magazines?
- The PF940SC accepts Glock 19 magazines but they will extend approximately 1.2 inches below the grip frame. While functional for range use, this defeats the concealment advantages of the subcompact platform. For carry purposes, stick with Glock 26 10-round magazines for optimal concealment.
- Can I return it if it doesn't fit my slide?
- Due to the nature of 80% frames, returns are not accepted once machining has begun. However, if you receive a frame with manufacturing defects, Polymer80USA offers a 30-day warranty for replacement. Always test fit components before beginning the milling process to ensure proper compatibility.
