Between the 2 the Bersa wins. Nothing personal against the P22 but they did have well documented problems with them. Are they fixed? I don't know but I do know there have been no such issues with the Bersa. Mine is 100% with MiniMags.
But I dearly wish the Ruger SR22 had been out when I bought my Bersa. Better gun from all reports, better sights and 2 mags.
