I own a Kel-tec 22 magnum pistol, PMR-30 and it shoots great. Others who own the same pistol call it the jamOmatic.
The reasons for jamming generally came down to ammo brand or bullet style, feed ramp and magazine problems. - some mags were found to have differences to the molded rib that holds the mag in place that caused a loose magazine. - injection die wear?
Try applying some case lube to the cartridges to reduce sliding friction, that might alter the chamber feeding geometry- a dab of Prussian blue, or felt tip marker ink applied to the feed ramp might show up a problem, too. Good Luck.
Once you have found something that alleviates the jams, you can hopefully then find the root cause for the jamming.
