Beretta U.S.A. Corp. has discovered a potential condition with Beretta .22 caliber NEOS semiautomatic pistols in which the pistol will fire even if the safety is activated and, in some cases, the pistols may fire if the safety is moved from the OFF to the ON position. Chances of either of these situations occurring is extremely remote and no injuries have occurred because of this condition, however, because of safety concerns relating to this situation, Beretta U.S.A. Corp. is immediately implementing a recall of Beretta .22 caliber NEOS semiautomatic pistols.
If you have a Beretta NEOS pistol, please send it to our Accokeek Maryland Service Center for repair. Instructions on how to send your Neos to Beretta is available at www.berettasupport.com/neos or by calling 1-800-BERETTA. Note: Some pistols are not subject to recall. Please visit www.berettasupport.com/neos to see if your NEOS has already been repaired.
Your pistol will be retrofitted, at no cost to you, with a replacement firing pin assembly. The new firing pin assembly can be identified either by a circle on the back of the firing pin that includes a red dot in the center, or by a vertical line (either version is suitable for your continued use) as seen in these illustrations:
Please make sure that your Beretta NEOS pistol is unloaded before delivery to the service center.
Do not experiment with your Neos pistol to see if it has the potential safety issue. Some NEOS pistols have already been repaired. If the firing pin for your NEOS looks like Version 1 or 2 above, you do not need to return it for retrofit. Please visit www.berettasupport.com/neos to see if your NEOS has already been repaired.
This is a good reminder that you should never rely on a mechanical safety. Cooper’s set of rules is the only reliable safety.
