Description
This is the magazine that makes the CP33 stand out from every other .22 handgun on the market. With 33 rounds in a single flush-fit magazine, you're loading up more than triple what most rimfire pistols carry, which means less time at the ammo box and more time doing what you came to do.
The quad-stack engineering is where the magic happens. Instead of the traditional single or double-stack layout, these rounds are arranged in four columns once you get past the initial double-stack section at the base. It's a clever system that Kel-Tec engineered to maximize capacity without making the magazine wider or longer than it needs to be. The clear polymer construction lets you see your remaining rounds instantly, so you know exactly how many shots you've got left without dropping the magazine to peek inside.
Building Your CP33 Magazine Supply
This is a factory Kel-Tec magazine built to their exact specifications and tolerances. That means it pairs perfectly with your CP33 pistol without any fit or feeding issues. The high-tensile steel spring and polymer follower work together to keep cartridges aligned and feeding smoothly, and the precision-machined cutouts on both sides of the magazine give you a rock-solid, wobble-free fit in the gun. If a round isn't seated quite right during loading, those side cutouts let you make quick adjustments. The removable floorplate is straightforward to take apart when it's time to clean.
Clear Polymer for Better Loading
That transparent finish isn't just for looks. It's a practical feature that saves you a step during mag changes. You can verify that your rounds are properly seated as you load, catch any potential issues before they become range problems, and do a quick count of what you're running without having to guess. For range sessions, training runs, or competition where you're cycling through multiple mags, this visibility makes a real difference.

Frequently Asked Questions
Is this magazine compatible with CP33 pistols from different production runs?
Yes. Kel-Tec magazines are manufactured to their factory specifications and tolerances, so this magazine will work with any CP33 regardless of when it was made. You'll get the same fit and feeding function as the magazines that came with your gun.
How do I load the quad-stack magazine properly?
Start by loading rounds into the double-stack section at the magazine base first, then continue into the quad-stack section above. The translucent construction lets you verify each round is seated correctly as you go. Take your time with the initial loads until you get a feel for the system, and a speed loader can make it much faster.
Will the clear polymer cloudy or get damaged from regular use?
The clear polymer is impact-resistant and built to handle normal rimfire use. It resists corrosion in harsh conditions and stays transparent long-term, so you can keep checking your round count shoot after shoot. Normal use at the range won't cloud or damage it.
Can I see my rounds clearly through the magazine during competition?
Absolutely. The translucent finish gives you a clear view of how many rounds you have left without removing the magazine from the pistol. This is a practical advantage during range sessions and makes quick ammo checks during competitions straightforward.
