An alert issued by Smith & Wesson warns that in some rare cases the thumb safety can move from the fire to the “safety on” position during firing.
The situation, the company cautions, would make the user’s handgun unable to fire until the manual safety is reset to the fire position and the phenomena have been reported by some using ammunition with a “high level of felt recoil.” Guns produced before April 4 are eligible for a free upgrade using a thumb safety that the company says is “less susceptible to the influence of ammunition weight, velocity and loads.”
To take advantage of the upgrade, Smith & Wesson is asking those with M&P 380 Shield EZ models with manual thumb safeties made before the affected date to call 1-800-331-0852 or email the company at MP380EZAdvisory@Smith-Wesson.com. A FedEx return label will be sent out to return the handgun to the factory at no charge.
In the same advisory, Smith also reminds users of EZ models not to use +P, +P+, or reloaded ammunition in their gun.
