Tonight I was cleaning my 9c, and went to reassemble it. The sear release was up.



I put the slide on the rails, started pushing it back against the spring, and something really bizarre happened. Pushing it back and reaching for the slide stop, I think I slipped and the slide flew forward.



I wound up with the barrel fully in the slide, but the guide rod sticking out of the front of the pistol at least an inch and a half. I pushed and prodded a bit, not too hard... and the rod snapped down into place, hard.



Okay, but...the slide is jammed solid. It won't move, forward or back. The takedown lever is halfway down, and can be wiggled but it won't move to full up or full down, and I'm not about to try to force it. The slide appears to be very slightly forward of normal.



Any clue? I'm going to call Smith tomorrow. Just wondering if anyone else has encountered this.

Solved it.



I took a dental pick and disengaged the sear lever through the mag well. That freed up the slide and let me remove and replace it normally.



I think what happened is that the slide got stuck between the sear engaging the striker at the rear, and the barrel lug getting hung up on the partially rotated takedown lever at the front.



I'm not entirely sure how it got to that position, though. I do know for a fact that I had flipped the sear lever up before attempting to put the slide on...I think what might have happened is that when I slipped and let the slide drop, the barrel lug traveled just far enough to get hung up on the takedown lever "shelf" (the part you can see rotate inside the frame when you move the takedown lever with the slide off).



That prevented the slide from moving to the rear, and the sear/striker engagement prevented it from moving forward. There was enough interference going on between the barrel lug and takedown lever that I could not rotate the lever out of the way, even though I could move the slide just a little bit.



What a relief! I was sure I hadn't broken anything, and I didn't want to force it and screw it up in the process. I surely didn't want to have to go through the hassle of sending it to the factory for what seemed like such an obvious thing.

In addition to what's been mentioned above, most polymer pistols have very short frame rails for the slide to move on. And they are not very thick either. Now compare that to metal framed pistols such as Sigs, 1911s, Beretta 92s, and CZs which all have thicker and longer frame rails. I believe the longer frame rails are beneficial to keeping the slide centered while reinstalling it. Just a thought.

The differences are huge as you pointed out, as I recall without looking the M&P has 4 contact points that are relatively small, where they old metal framed guns the rails often ran the entire length of the frame.
