Here is a video of the guys reviewing the CP33. The owner’s manual has a set of instructions and tips to avoid the issue, and the magazine is clear plastic so you can check it for issues before shooting. Still, some people have a hard time loading the magazine perfectly, especially the last few rounds. The magazine was redesigned, and it helped a lot. But they knew every intricacy of the gun. The factory beta testers ran the product nicely, with only the occasional minor complication. Traditional rules of gun-making say that 22lr doesn’t run well in handguns, it doesn’t like long magazines, and it can’t be double stacked in a magazine. It’s a very large, very lightweight semi-automatic pistol that holds 33 rounds of 22lr in a sort of double or triple-ish stack magazine. The CP33 is a 22lr pistol that looks like it belongs in a futuristic sci-fi action film complete with aliens and a damsel in distress.

Improper loading creates rimlock which is when the top cases’ rim is stuck behind the bullet beneath. I personally love the gun, but my buddy hates it. They load different from most magazines and there can be a learning curve to learn how to do it right. Some people just have a hard time loading the mags well. The ammo won’t feed though and the gun jams. Improper loading creates rimlock, which is when the top cases’ rim is stuck behind the bullet beneath. The magazine of the Kel Tex CP33 can jam if the magazine isn’t loaded properly. Apparently, the second factory run of mags runs smoother. My sister-in-law and I had zero problems firing the CP33 at the shooting range. The clerk asked for input on its performance because they had issues and the manufacturer sent them some new magazines as a fix. I rented a Kel Tec CP33 at a local range.
