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.
Brand new factory ammo
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.
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.
