Kel Tec CP33 22 LR 33RD 5 5IN Threaded Green

About this product

The Kel-Tec CP33 is one of the more unusual pistols on the rimfire market: a polymer-framed .22 LR built specifically around a 33-round quad-stack magazine, in this case finished in green. Kel-Tec designed it as a high-capacity range and competition gun rather than a traditional target pistol, and the spec sheet reflects that.

What's the actual capacity, and how does it fit 33 rounds in a pistol magazine?

The CP33 uses a four-row, quad-stack magazine design that Kel-Tec built specifically for this platform, which is how it reaches 33 rounds in the standard magazine (with 50-round extensions available separately from Kel-Tec). The magazine release is a heel-catch style rather than the more common button release, a deliberate choice that keeps the grip housing narrow enough for the stacked magazine body.

What does the threaded barrel and sight setup look like?

This variant ships with a 5.5-inch barrel threaded 1/2x28 with a 1:14 twist, so a suppressor or muzzle device threads on without modification. Sights are adjustable fiber-optic units for both windage and elevation, and the top of the receiver carries a Picatinny-style rail with M-LOK slots on the dust cover for lights or other accessories. Overall length runs about 10.6 inches, and the polymer frame keeps unloaded weight to roughly 1.5 pounds.

How does the trigger and charging handle work?

Kel-Tec put the charging handle at the rear of the receiver rather than on the slide, a layout choice tied to the CP33's fixed-barrel blowback design. Reports on the factory trigger describe a comparatively crisp break in the neighborhood of 4 pounds with minimal overtravel, which matters for a gun that's often run fast in run-and-gun rimfire matches. Ambidextrous safety levers sit on both sides of the grip for right- and left-handed shooters.

Who is the CP33 built for?

This is a range-toy-meets-competition-gun: shooters who want a high round count between reloads for training magazine changes less often, rimfire steel-challenge and speed shooters who want extended runs on a stage, and anyone who simply likes shooting a lot of .22 LR without constantly topping off. It is not a concealed-carry pistol given its size and magazine profile.

What should California buyers and first-time firearm buyers know?

As a firearm, the CP33 cannot ship to a home address — it ships to a licensed FFL dealer where you'll handle the transfer paperwork and background check in person. Because California maintains its own handgun roster separate from federal rules, and high-capacity magazine rules vary by state, California buyers should confirm current compliance for this specific model and its magazines with their receiving FFL before ordering. Checkout here runs through secure checkout, and we don't advertise stock counts or shipping timelines since either can shift before your order ships.

What else does a California transfer involve?

Beyond roster and magazine questions, California handgun buyers should plan for the standard 10-day waiting period between the background check and pickup, a valid Handgun Safety Certificate unless you qualify for an exemption, and a Department of Justice-approved firearm safety device that must accompany the sale. Your receiving FFL will walk you through the current paperwork, but budgeting the extra time and the small cost of a locking device up front makes the pickup appointment go a lot smoother.

How does the CP33 compare to Kel-Tec's other rimfire pistols?

Kel-Tec also makes the PMR-30, a slimmer .22 WMR pistol with a 30-round magazine. The CP33 trades that caliber for standard .22 LR ammunition, which is cheaper and more widely available, while pushing capacity even higher with its quad-stack design. If you're deciding between the two, ammunition cost and availability is usually the deciding factor rather than the small difference in capacity.
