My 9 was the same way when I first got it. The first few times I cleaned and lubed it forgot to look at or clean the ejector. It had a piece of metal stuck in the hook. I've noticed since that the hook is the dirtiest of all the parts in the pistol when I break it down for clean and lube. Also when I pressed on it it didn't have much movement. Got some penetrating oil into the sides and loosened it up. When I get time I'll take it off and clean it good as I don't think it should need oil being under spring tension. I thought for several hundred rounds it was the ejector but it ejects great now. I also have the Apex DCEAK and the new poly trigger so now it's as it should have been out if the box. Accuracy is much much better.

The M&P 16lb recoil spring is common to both the 9mm and the 40SW. With ammo ranging from 9mm 115gr to 40SW 180 gr, the spring works best in the middle of the spectrum. It is too strong for the light 9s and too weak for the heavy 40s. This translates to weak ejection for the former and increased felt recoil for the latter. Both ISMI and Wolff springs offer reduced power and extra power springs. I use 14lbs for my 9mm and 17 lbs for my 40SW.

Our 9mm has this issue some times. A spring change would be a nice easy fix.
Keep us updated.

I have a 52 that did the same thing. Sent it back to Smith and now ejects 2 o'clock and about 5-6 feet, now at bullseye matches the guy to my right has to deal with it.

Yes, the reduced power recoil spring solved my "brass to the face" problem. It even cured the "aluminum to the face" problem that I was having with Blazer ammo which was the worst offender of all.
Incidentally, the Wolff part number for the 14 lb spring and guide rod is 53314. The Wolff spring is uncaptured and requires the use of a different guide rod than the one in your M&P. If you want to save buying the guide rod, you can buy a 15 lb spring from ISMI. It will fit on your existing guide rod but it's a pain to install and you'll have to shoot no lighter than 124 gr.

I've been around auto loading pistols everytime I go to the range. I own a M&P. buddies own rugers, spring fields and 1911's. and no one I know of ever has that problem. Don't thinks the auto loaders fault.
Now my sks, that's different. There's never any telling.

The only input I have on the subject is to shoot a new gun at least 500 rounds with full power ammo before deciding there is something wrong with the gun.
