I bought a new Beretta 21 on Saturday and took it to the range today. The owner's manual said to use standard velocity ammo, as I suspect that the high velocity ammo is too hot and Beretta stated that the hot stuff would shorten the life of the gun. I managed to get the gun to function most of the time using the expensive Federal Gold Medal Match ammo, at around $6.00 a box, it should work.
I had some cheap CCI stuff and some German ammo to get the initial breakin started. Man, what a jammo matic!!! :x Even with the Federal Gold it was not 100% percent reliable. The gun was oiled before I took it to the range, so that was not the problem. This gun had all the classics of jamming, stove pipes, failure to feed, double feed, failure to clear the clip. The gun was cleaned several times during the 150 round test. It also had the slide try to jump up and out when the barrel was raised to start the initial round on one occasion, I tried chambering it with just the slide pulled back, tip up the barrel, etc. That gun was major unreliable, it scared me so bad that I traded it today for a Springfield XD in 9MM.
I had a Lorcin .22 pocket pistol back in the mid-1990's that would only work with Remington high velocity, and then it would jamb after the 3rd clip without a cleaning. As far as I am concerned these .22 cal. pocket pistols are only good to shoot at tin cans, and you would be a heck of alot better off with a Ruger Mk. 2 or a Browning Buckmark pistol to ventilate beer cans instead, at least they work reliably.
I think the Beretta Model 21 might work if it was in the reliable .25 cal. ACP (my Raven .25 cal never jambed in 600 rounds), or use only .22 cal high velocity copper coated ammo, but that would shorten the gun's life span. No way will I ever buy another .22 cal. pocket pistol!!! :shock:
