I have two, both function flawlessly as long as I don't use Winchester or ANY Remington ammo. CCI seems best. If it's new just send it to Beretta and they can go through it, that would be the best thing to do.
Mine is temperamental...the guy who sold it to me gave me a steal on it, because it jammed all the time & he couldn't get it to work. I got it to work fine with CCI Mini Mags, and he felt kinda remorseful after finding that out.
Since I haven't been on here in awhile maybe it's time for one of my pistol rants. LOL
Pocket 22 autos are some of the most unreliable pistols made. Everything has to be perfect and even then they may not work all the time.
They require a strong wrist and proper firing grip, even a slight limp wrist will cause problems, they must be clean and well lubed. The magazines and springs must be clean and well lubed and checked for damaged feed lips and must be loaded properly to allow the rounds to feed. The most reliable 22 autos like the Ruger and the HiStandard have the magazine in the gun at quite and angle, this is for feeding purposes. The 22 rounds have big rims on them and they will tend to hang up on each other as they feed if the magazine is not slanted enough to ensure the top round is ahead of the one below. With some of the compact 22 autos this is compromised by having the mag more vertical to save space but that leads to feeding problems.
Then there is the issue of the quality of 22lr ammo, only the very very expensive target ammo has any real quality, even the best of the generic stuff is spit out of the factory at millions per day not to mention the econo 500 rounds in a square box mart stuff. This is ammo made for plinking, small game hunting, or target shooting, not life and death.
All this adds up to the main reason serious self defense instructors never recommend the 22lr for serious use. It's not so much the stopping power issue, it is the reliability issue. When this gets discussed someone will always bring up how the 22lr is used by hit men the Mossad or whatever and that is true, but these are all offensive actions not defensive, big difference.
Even after all that any firearm is better than none if it will fire at least once.
