Smith & Wesson released a safety alert today for all M&P Shield firearms manufactured before August 19, 2013.
Smith & Wesson has identified a condition where the trigger bar pin could damage the lower trigger in certain M&P Shields in a way that may affect the functionality of the drop safety feature of the firearm, potentially allowing the pistol to discharge if it is dropped.
Any unintended discharge of a firearm has the potential to cause injury, and we ask that you STOP USING YOUR PISTOL IMMEDIATELY UNTIL IT HAS BEEN INSPECTED AND, IF THE CONDITION IS FOUND, REPAIRED.
This Safety Alert applies to all M&P Shield pistols manufactured before August 19, 2013. We believe this condition is largely limited to recently manufactured M&P Shield pistols. However, out of an abundance of caution, we are asking all consumers of all M&P Shields manufactured before August 19, 2013 to immediately inspect their pistols for this condition.
You can read the rest of the safety alert here, with information and photos on identifying pistols that require repairs. For the record, my Shield does not require repair.
