Mgpl 9mm double stack magazine +2 base pad extension for Glock handguns. These are intended for use with an aftermarket magazine manufacturer which cannot be named due to trademarking. These are 3D printed with a high strength engineering resin. Thoroughly tested with 1k+ rounds. Perfect addition for your P80 and sure to impress others at the range.

PLEASE READ: The magazines pictured are not included with this product and are shown for demonstration purposes only.

Installation instructions: 
1. Remove the original base plate.
2. Dry fit the extension by sliding on and off a few times.
3. Add blue or red Loctite to the interlocking channels and firmly slide the extension into place. Let cure 24 hours before using.

DISCLAIMER: Due to the magazine's design, Loctite is required to keep the magazine baseplate extension secured. If it does come lose while firing, the magazine spring will keep the magazine intact. However, stop using immediately and repair with more Loctite. Red Loctite is preferred. This should be considered a permanent modification to the magazine.

The Mission

We strive to provide custom design and fabrication at competitive prices.

The Legal

We will not sell 3D printed firearms or anything regulated by U.S. government agencies. You are responsible for understanding and following all local and federal laws. See Terms and Conditions section linked in the footer for more details.

The Resin

Traditional 3D printed resin is fragile and becomes brittle with prolonged UV exposure. Our 3D printed products are made with SirayaTech Build, which is a high-strength engineering resin designed for prototyping structural models. 'Build' offers impressive properties at 50 Mpa tensile strength, 8% elongation at break and a heat deflection rating of 165 degrees Fahrenheit. It will not become brittle with prolonged UV exposure and is also tappable. Our commercial products have all been tested for comptability and durability to ensure that you receive high quality accessories.

Return Policy

We accept returns! If you are not happy with your purchase, we will send replacement parts or provide a full refund. Please contact us with any questions you may have. See Return, Refund and Exchange Policy linked in the footer below for more details.
