I have a Beretta 950 chambered for .22 short. After the first few hundred rounds were fired through it it has been 100% reliable with both Remington and CCI ammo.
I have roughly 0% faith in it's ability to stop an attacker, but even so it's better to have along than nothing on those many occasions in summer when only the very smallest gun can be concealed under hot weather clothing. After all any gun poses a threat to an attacker, nobody wants to be shot with any gun, not even a .22 short.

Good to hear of the reliability you are experiencing with your 950.
They were really handy with the longer barrel, too. I'd be tempted to change to the longer barrel. A very handy package, for all sorts of utilitarian purposes.
Paco Kelly sells a .22 cal bullet swager which enhances accuracy and other performance. One is a tool which creates a shallow hollow point, the other creates a post/hollow point. I plan to try the shallow type with CB Shorts. Reports I have been given rave about how well these tools work.
I suspect that Militec-1 lubricant would aid reliable extraction too, once it hardened the metal, and was cleaned off...the surface dried. It hardens the metal 17x, and works after the oil transport medium is long gone...a dry lubricant, a metal conditioner.
