Just like the title says, my trigger bar assembly moves left to right and when it does that it fails to engage the sear causing a failure to fire.
I have put twenty one hundred rounds down the barrel. Can you please help me Thank you |

Through the full motion of the trigger the trigger bar is supposed to move from left to right, there is an angle on the slide that forces it to. Is it doing this while disassembled? If so the only thing that I would check would be to see if the tail of the trigger bar in properly installed in the sear block. |
| How old is your gun? The FTF sounds like sear flutter due an older worn sear spring which S&W addressed by using a much larger sear spring and pin. If you have an older M&P with the smaller sear spring/pin then I'd swap that out for a new sear housing block, spring, and pin first. |
