Recently purchased a 4.25" M&P 2.0 TFX, after a few range visits now I notice my shots would inconsistently pull left on the target at 15-20 yards. After cleaning the pistol I looked at the back of the slide and after racking it it stays back a marginal amount then once I squeeze the trigger *Snap Cap in chamber* the slide moves forward 0.015-0.025" and the rear shifts leftward. I would estimate it's because the striker spring is new and strong but has anyone else experienced this and does it go away? the pistol is surprisingly accurate when the slide does return to the full forward position.
