The Texas Department of Public Safety stopped issuing and training with the recently acquired M&P9 pistols from Smith & Wesson.
Texas DPS picked up 120 of the M&P9 pistols with the intent of issuing them to the current recruit class that began training in January. However, the Texas Tribune reported that feeding and ejection issues, combined with “slight movement” in the guns caused agency to pull the weapons and issue older SIG P226 pistols.
The Texas Tribune does not explain the slight movement other than to say is was measured at less than 10 microns (0.01mm) and could affect accuracy. The paper does say the movement developed after the firing of about 3,000 rounds.
It does not appear that the Texas DPS released any quantitative data on the number of malfunctions experienced, nor if the problems were with only specific guns or with a certain kind of ammunition.
