Key Features
This 33rd magazine isn’t just about adding rounds; it’s about intelligent engineering. We’ve focused on creating a magazine that feeds reliably, even under stress. The follower is meticulously designed to maintain consistent pressure on the cartridge stack, minimizing the chance of malfunctions. The magazine body utilizes a reinforced polymer blend, striking a balance between durability and weight reduction. The internal geometry is optimized for smooth feeding, and the magazine disassembly is straightforward for easy cleaning and maintenance. We’ve extensively tested this magazine across various platforms to ensure consistent performance. The magazine baseplate is slightly extended for a more secure grip during reloads, and the witness holes clearly indicate remaining capacity. This magazine is built to withstand the rigors of frequent use and demanding shooting scenarios, offering a significant upgrade over standard capacity magazines.
Compatibility is key, and this polymer80 extended magazine is engineered to work seamlessly with a wide range of platforms. It’s fully compatible with Glock 17, Glock 19, and Glock 26 pistols in 9mm. It also supports Polymer80 PF940v2, PF940C, and PF940SC frames chambered in 9mm Luger. This magazine is designed for use with standard Glock magazine releases and does not require any modifications to your firearm. While primarily designed for 9mm, attempting to use other calibers will result in malfunctions and potential damage. We’ve tested compatibility across multiple generations of Glock pistols, ensuring consistent functionality. It’s important to note that while compatible with Polymer80 frames, proper fitting and function checks are always recommended after assembly. This magazine is not intended for use with .40 S&W or .45 ACP firearms. Always verify your firearm’s compatibility before purchasing.
We understand that reliability starts with quality materials. This magazine is constructed from a high-strength, reinforced polymer that’s resistant to cracking, warping, and impact damage. The internal spring is made from high-tensile steel, ensuring consistent pressure and reliable feeding over thousands of rounds. The surface finish is a durable, matte black that provides a secure grip and resists scratches. We’ve subjected this magazine to rigorous testing, including drop tests, temperature extremes, and prolonged use, to ensure it can withstand harsh conditions. The baseplate is securely attached and designed to prevent accidental disassembly. This magazine isn’t just built to hold rounds; it’s built to last, providing years of dependable service. The materials were selected to minimize weight while maximizing strength and durability.

How It Works
Integrating this 9mm high capacity magazine into your Polymer80 pistol build is a straightforward process. First, ensure your Polymer80 frame is fully assembled and functioning correctly. During the build process, you’ll need to ensure the magazine well is properly sized and free of any obstructions. When installing the magazine, insert it firmly into the magazine well until it clicks into place. A proper fit should allow for easy insertion and removal without excessive force. After installation, perform a function check by manually cycling the slide several times to ensure the magazine feeds rounds correctly. Pay close attention to the follower’s movement and ensure it’s consistently pushing rounds into the chamber. If you encounter any resistance or feeding issues, double-check the magazine well for debris or imperfections. It’s also crucial to ensure the magazine release button is functioning correctly, allowing for quick and easy magazine changes. Regularly clean and lubricate the magazine to maintain optimal performance. Remember to always follow all safety guidelines when handling firearms and magazines.
Frequently Asked Questions
Is it legal under United States federal law to purchase a extended magazine?
Yes, under current United States federal law, purchasing a 33-round magazine is generally legal. 80% frames, and components like this magazine intended for use with them, are not considered firearms until fully assembled and functional. However, it’s crucial to understand that state and local laws vary significantly. Some states have restrictions on magazine capacity, and it’s your responsibility to research and comply with the laws in your jurisdiction before making a purchase. Always prioritize legal compliance.
Can I order this extended magazine without going through an FFL dealer?
Yes, you can order this extended magazine directly from p80source.com without going through a Federal Firearms License (FFL) dealer. This is because the magazine itself is considered a component part, not a firearm, under federal law. The exemption applies to parts intended for use in building non-regulated items like 80% frames. However, please be aware that this exemption only applies to the magazine itself and does not extend to the complete firearm once assembled.
What other components will I need alongside this extended magazine for a complete build?
To complete a Polymer80 pistol build, you’ll need several other components in addition to this magazine. These include a Polymer80 frame, a 9mm slide, a 9mm barrel, a trigger assembly, a magazine release, a slide stop, a rear sight, a front sight, and a grip. You’ll also need various pins, springs, and other small parts. Don’t forget essential tools like a drill press, punches, and a vise. p80source.com offers complete build kits to simplify the process.
Is this product compatible with aftermarket Glock components?
Yes, this magazine is generally compatible with many aftermarket Glock components, particularly those designed for Gen3 Glock pistols. Many aftermarket slides, barrels, and triggers are designed to function seamlessly with standard Glock magazines, and this 33-round magazine is built to those same specifications. However, it’s always recommended to verify compatibility with the specific aftermarket components you intend to use. Some components may require minor adjustments or modifications to ensure proper function.
