The Bersa Firestorm 22 is the first gun I've purchased in decades. Received the gun fairly clean, no heavy grease on it, with a little debris in the barrel. Cleaned the gun out of the box and took it to the range the next day. Loaded the magazine with CCI mini-mag, pulled the trigger, the hammer fell - nothing. Ejected the shell, fired again, nothing happened. The range master took a few tries and the gun started firing after three attempts. He recommended pulling back the hammer and try striking the round again.
The Bersa worked almost flawlessly after the misfire with 55 rounds of CCI mini-mags and 100 rounds of Remington Golden Bullet HP. There were a few misfires, but, pulled back the hammer and they fired on the second try. Do not waste money on Federal Premium Gold Medal, put 50 rounds through the gun, every round failed to eject, except a string of three in the last few shots, about a third had to be pried out of the barrel after firing. Held the gun as tightly as possible to allow the force of the round to eject the Federal's, not much help. Had about 8 rounds of Winchester, the first couple jammed, the rest fired without mishap, not enough for a real test.
The grip is very comfortable and I really enjoy firing the gun. The gun is far more accurate than I am at 30 feet, the range master proved that. Wouldn't trust the gun for defense due to the misfires. Will shoot it a lot at the range.
