Default Brand New M&P 9mm Shield will not go into battery

Got home with my brand new M&P 9mm Shield - I loaded up a magazine and tried to put the gun into battery. The slide would not go all the way forward.

I called S&W Customer Support - their idea was to clean the gun since I hadn't done it yet. I cleaned the gun. (It wasn't dirty - no grease or gunk in the chamber). I asked the customer support rep if they test fire every gun at the factory, which he said they do - 2 mags worth. I'm not sure how the test fired this one?

I think they didn't machine the chamber deep enough so when the shell casing seats, it's not in deep enough.

Does anyone know how deep it should be?

S&W has told me to ship it to them and they will look at it.

Pictures of the issue:

Are these reloads?
Have you tried a completely different bullet design to see if it goes into battery?

Brand new factory ammo
Factory "reloads"
Reloads made at home

What weight bullet.

I had a 9mm that didn't like reloads of any sort , just factory and just .355 diameter bullets. It didn't like 147 grain bullets either .
It shot fine with 115 gr and 124 grain jacketed factory ammo. But not my reloads and not cast bullets .
Ammo with .356 dia. bullets did just as yours does and wouldn't close. That gun had a tight chamber and hardly any throat. I bet your's has a too tight chamber or maybe just not not quite deep enough. Should be an easy fix but it shouldn't have shipped out like that.

Brand new ammo, tried Remington, UMC and some Korean stuff. Same result. I don't think it's the ammo.

Does anyone know how deep the throat is supposed to be machined to in the chamber? Mine is 15.1mm, .595", I've seen some generic diagrams that show it needs to be around 16.1mm.

I have a m&p 9 back in 2012 had the same problem.115 ball would chamber barely hollow points not even close to chambering. Headspace good on a empty resesized case.There was almost no throat. 115 ball would just touch the rifling you could see rifling marks on the bullet.

Ask S&W to send a Fedex label to send it in for inspection. Include a copy of your photos, etc.

My Shield measured .615"
Did you rack the slide and let it's full force so the extractor didn't bind? On mine, if I ride the slide forward without letting it rack, it will easily remain OOB.

Update:

Fed Ex brought me a box from Smith & Wesson's warranty department today. They replaced the barrel and test fired the pistol.

Tomorrow I plan to go the range during lunch and test her out.
