M&P9 Questions

I recently purchased a M&P9 range kit and tried it out at the range. Prior to shooting, I field-stripped the pistol, cleaned it and re-lubed it with gun oil exactly as directed by the owner's manual. This is my first restricted firearm.

For every shot I put downrange, I needed to rack the weapon again, and about once every ten shots had to remove the magazine to clear a jam. The issues encountered were:
-Failure to eject spent cartridge, cartridge remained in chamber (however, the firing mechanism was able to reset, creating a scenario where I successfully fired a round, but the next trigger pull made a "click" instead of a boom)
-Double feeds
-Spent cartridge lodged in breech, preventing return to battery (failure to fully eject spent cartridge)

My thinking is that a mechanical problem prevented the slide from fully cycling, as it was able to come back far enough to reset the firing mechanism, but not far enough to avoid one of the above problems. For every successful shot fired, one of these malfunctions occurred. Currently my line of thinking is to clean the gun and re-lube all contact surfaces between the slide and the frame. A range attendant recommended using much more oil than I had previously.

When manually cycling the firearm, all of my snapcaps ejected successfully with a quick, sharp pull on the slide. I feel I can safely rule out issues with the ejector spring or the ejector itself.

Does anyone else have similar experiences, or thoughts as to other potential issues I should explore?
 
mine ran like a top out of the box. 2 failures to go into 100% battery in the 1st 100 rounds (it was just a hair short of being in battery), since then, perfect.
 
Ammo. What ammo are you using? Sounds like the same issues I had with a bad batch of reloads.

Same here. What ammo type? My sons 9 range kit has ran flawlessly since new and even at -15c with many types of factory ammo 115 and 124,s even blazer aluminum 115s. Winchester had a bad deal going on whitebox 115s a few years ago. Let us know the ammo make, type, weight, etc. Cheers, RTS.
 
Mine runs great, and I know its a simple break down on this gun, but is it at all possible something didnt go back together correctly when you initially did the break down and cleaning?
 
I never had a failure to eject ever with mine. Thousands of rounds fired. Take it back, sounds like you got a lemon.

I have, but apparently that's the way it goes when you load Remington brass often enough that it no longer has a decent rim for the extractor to grab - my bad.

I'm at 33000 rounds plus + no failures that weren't caused by bad ammo, the gun doesn't even look bad either.
 
Sorry for the slow reply, I really appreciate all the advice. The ammo I used was Remington UMC, the yellow-box stuff. I believe they're 115gr. I re-examined the pistol and I wasn't able to find anything out of order. I took it down and re-assembled it according to the manual.

I applied more oil, the slide moves a lot smoother now. I haven't been out to the range a second time, that'll probably happen in the next few days.

I have very similar problems with mine durring the first 50 rounds. 2 FTE's. Everything was fine after that. Think it just needed to be broken in a bit. Im now shooting AE 124gn and have had no issues, except running out of ammo.
