While the KelTec® CMR30™, CP33™, and PMR30™ are popular for their lightweight design and high magazine capacity, many users struggle with accidental magazine releases. The TANDEMKROSS “Maverick” Extended Magazine Bumper offers an oversized grip that protects the heel release button, putting a stop to accidental magazine releases while improving the consistency of positive magazine changes.


The ergonomic design fits the natural shape of the hand, ensuring a more comfortable and consistent magazine seating for all users. The extended magazine base pad is made of lightweight Zytel and features a skeletonized design to increase grip surface area with minimal added weight. Should the magazine get stuck, the skeletonized design offers the user a ring pull for easy pulling from the magazine well.


This drop-in magazine shoe easily attaches to the bottom of the KelTec® CMR30™, CP33™, or PMR30™ magazine using the factory-installed base pad attachment. It does not require glue or gunsmithing and can be easily installed by the user.


Don't forget, all TANDEMKROSS products are Made in the USA and come with a LIFETIME guarantee!


**Dealer Pricing available for all TANDEMKROSS products. This product offers very competitive pricing, great margins and is shelf ready for display.

    PMR/CMR 30 Magazine Base Extension

    Posted by William on 21st May 2022

    Bought these base extensions to assist in magazine changes. I am not schooled in the type that are standard on Keltec guns so I needed a little help. These bases work outstanding, they were just what was needed, I do recommend this product as a "Must Have" if you own a Keltec PMR or CMR 30.

    Maverick Extended Mag Bumpers

    Posted by Michael R on 10th Mar 2022

    I ordered 2 packs (w 2 Mag Bumpers/ pack) bc I own both a CPR30 and a CP33, and I find that the position of the Mag Release (at the Heel of the Grip) is not in a convenient location nor and when the Mag Release is pressed, and the magazines do not just “drop free” of the Grip, u must use your fingers to pinch the magazine and to pull it out. So I installed the Maverick Extended Mag Bumpers (super easy by the way), and now it is a lot easier to remove the magazine from the mag well.

    Should be on factory magazines

    Posted by James on 6th Feb 2022

    Well made and makes it easy to unload spent magazines or clear jams that will happen from time to time with this magazine design. This should be on factory issued magazines.

    Great Product

    Posted by Rush on 1st May 2021

    I bought 2 sets to use on all my magazines. I like the loop, I put my finger in the loop, press the mag release with my thumb and pull out the magazine. This is my preferred way to remove the magazine that sticks in the gun and has to be pulled out. (I guess if the mag holds 33 rounds, the mag doesn’t need to “drop”l) Since I use the gun only for plinking and target shooting, the loop doesn't get in the way. I do believe though that the item would sell with and without the loop.
