Just bought a new 2.0 M&P (not compact). I haven't gotten it to the range yet but did basic field strip to familiarize myself with it and check out the internals. When reassembling, the slide would only go about 3/4 of the way back and would then hit a wall and refuse to go any further rearward. If I put a little force into it, whatever was making contact would cause the trigger to move. I made sure that the takedown lever was all the way down. I eventually got it back together by wiggling the slide a little and trying repeatedly until it got past whatever was in the way. I repeated slide removal and reassembly several times to see if it continued and ran into this wall every time. I'm sure this is something simple that doesn't require a trip to Massachusetts. Tips? Does something need a little tweaking?

Its your slide stop.

You bumped it up part way or all the way.

Your ejector hit the back of the slide cover.

Sometimes I have to lift or wiggle the back of the slide to get past the ejector.

This, I have done it several times . Just push it back down and then you should be fine.

Is your sear deactivation lever in the lowered position? That is necessary for reassembly.

Are you absolutely certain your RSA (return spring assembly) is seated perfectly centered?

Thanks for all the replies. Somehow, the problem went away after reassembling a few times. This gun definitely deserves a range report. I'll try to post one sometime this week. I'm very pleased with this gun.
