Hello everyone, this is my first post at the S&W forum. I am having a problem with the takedown lever on my M&P Shield .40 Performance Center. The problem is that the takedown lever will rotate even when the slide is fully closed as long as the trigger is pulled. I did verify that the takedown lever is fully seated in the block and it appears to still have the little tab on the edge that is supposed to keep it from rotating. Has anyone seen this before? Also, I was wondering what would be a reasonable turnaround time for a repair on this model gun? I know Ruger turned around a pistol in 3-weeks, I'm hoping that it won't take too long.
