Product Overview
This plus one extension comes with two stainless steel dowel pins to secure the magazine body to the extension. This part replaces both your stock floor plate and locking plate and it can work with your existing seven round magazine spring, although the slide may not reliably lock back if it's worn. And now we offer the choice of adding a longer spring to ensure proper slide operation!
We designed this extension to be more ergonomic and secure than the factory option. The last two images in the gallery show the original KelTec offering. KelTec's product has a metal prong that sticks out the back and tends to interfere with the hammer spring assembly when inserting the magazine. Depending on how you insert your magazine, it can even prevent the magazine from seating properly. However, our design provides plenty of clearance so you know your magazine will insert properly.
We now offer this product in two materials, PA6-CF20 (carbon fiber filled nylon) and Polycarbonate. Polycarbonate has greater tensile strength and impact resistance compared to PA6-CF20. The cosmetic appearance of Polycarbonate has a glossy surface finish and PA6-CF20 is matte. The PA6-CF20 parts are annealed post print for improved impact resistance.
You can also purchase the spring only if you already have our +1 extension and want to refresh your magazines!
Note: Firearm and magazine not included. This product includes the magazine extension/pinky rest and two stainless steel dowel pins.
Installation:
Start by removing the floor plate and locking plate from your magazine and set them aside. This product does not use the locking plate to secure the floor plate in place. Instead, you will use the included dowel pins. Next, compress the factory spring into the magazine body past the first witness hole, then slide the magazine body onto the new floor plate and release the spring. Finally, push the two dowel pins into the holes near the rear of the magazine body. You can use needle nose pliers to get them started and hammer them into place using a punch.
Removal:
To remove the floor plate, you can use a 1.5mm punch on the backside of the pins to tap them out. The pins are only removable through the top of the floor plate. The holes are too small on the bottom of the floor plate. Next, slide the magazine body back slowly until the floor plate can separate from the shell.
