IMG-20251120-WA0046

When it comes to building your own firearm, understanding the differences between popular frame kits is essential. Two of the most sought-after Polymer 80 kits are the PF940SC and PF940C. Both are designed for Glock 17/19 compatibility, but they serve slightly different purposes and appeal to different shooters. In this article, we will explore the key differences between the PF940SC and PF940C, so you can make an informed decision for your next build.

What is the PF940SC?

The PF940SC is a compact 80% frame kit designed for those seeking a slightly smaller, more concealable firearm. The “SC” stands for “Sub-Compact,” which is evident in its shorter grip and overall reduced size compared to full-size frames. The PF940SC is popular among concealed carry enthusiasts because it allows for easier carry while still maintaining adequate magazine capacity. This frame kit is compatible with standard Glock 19 components, making it a flexible option for builders who want a reliable, compact build.

The PF940SC is also known for its ergonomic design. The grip has been carefully shaped to provide a comfortable hold, even for extended shooting sessions. Additionally, the PF940SC frame offers excellent durability, as it is constructed from high-strength polymer, ensuring that your build remains sturdy and reliable under heavy use.

What is the PF940C?

On the other hand, the PF940C is a compact frame kit, where the “C” simply stands for “Compact.” While it shares many similarities with the PF940SC, the PF940C is slightly longer and features a larger grip, making it more suitable for shooters who prioritize control and accuracy over ultimate concealability. The PF940C is compatible with Glock 17/19 components as well, allowing for a versatile build that can accommodate a variety of slides and barrels.

Shooters often choose the PF940C because it offers a middle ground between a full-size frame and a sub-compact option. The added grip length can improve handling and recoil management, which is particularly beneficial for new shooters or those planning to use the firearm for target shooting or home defense.

Key Differences Between PF940SC and PF940C

Understanding the key differences between the PF940SC and PF940C is critical for choosing the right frame for your build. Here are the main distinctions:

Size and Concealability

The PF940SC is shorter and more compact than the PF940C, making it easier to conceal. If your primary goal is a discreet carry firearm, the PF940SC is likely the better choice. Conversely, the PF940C offers a longer grip and slightly larger frame, which may be less concealable but provides more control.

Grip Comfort

While both frames are ergonomic, the PF940C has a slightly longer grip that allows for better handling, especially for shooters with larger hands. The PF940SC is more compact, which may be ideal for those with smaller hands or who prioritize a lightweight design.

Magazine Capacity

Due to its reduced size, the PF940SC may have a slightly lower magazine capacity than the PF940C, depending on the magazine used. Both frames accept standard Glock magazines, but users often prefer the PF940C for extended magazine options and better grip ergonomics.

Recoil Management

The larger grip and frame of the PF940C allow for slightly better recoil control compared to the PF940SC. While both frames perform well, shooters who want a more stable shooting experience may find the PF940C more suitable for high-volume shooting or competition use.

Build Flexibility

Both the PF940SC and PF940C are compatible with Glock 17/19 slides and parts, but the PF940C may offer a slightly wider range of customization options due to its slightly larger frame. The PF940SC, however, is ideal for those looking for a streamlined, compact build.

Why Choose the PF940SC?

Choosing the PF940SC comes down to your priorities. If concealability, lightweight design, and a smaller profile are your primary concerns, the PF940SC is the ideal frame. Its compact design does not compromise reliability or performance, making it a favorite among concealed carry enthusiasts. The PF940SC also allows shooters to enjoy the versatility of a Polymer 80 build without sacrificing comfort.

Why Choose the PF940C?

The PF940C is perfect for shooters who value handling, control, and slightly higher magazine capacity. While it is less concealable than the PF940SC, it provides excellent ergonomics and recoil management, making it an excellent choice for home defense or range use. If you want a compact frame that balances size and functionality, the PF940C is a solid option.

Conclusion

In summary, both the PF940SC and PF940C offer high-quality, durable 80% frames that allow you to build a custom Glock-compatible firearm. The PF940SC excels in concealability and compact design, making it ideal for daily carry, while the PF940C provides enhanced grip, control, and flexibility for shooters who prioritize handling and performance. By understanding the key differences between the PF940SC and PF940C, you can select the frame kit that best suits your needs and build a firearm that aligns with your shooting style and preferences. The PF940SC remains a top choice for those seeking a compact, reliable, and versatile frame that doesn’t compromise on quality or ergonomics.
