I've a  S&W M&P I've had for years; it's been a great gun.

Today I happened to cycle the slide to remove a round while the mag was ejected. It didn't fly clear, in fact, it fell down the mag well!  I thought, "That's weird, I must not have racked hard enough". I tried again, same result. Next I left the mag in and when I racked the slide it flew well clear. Repeated the whole process with the same results.

OK, what's the problem?

Loaded round? Nt seeing a problem as long as it ejects fine while firing.

It's not normal.

My Shield does that. I decided that the upward pressure of the next round or follower forces the casing out the ejection port, but without a mag in it, gravity takes over as often as not and the round/casing slips down off the extractor prematurely.

I decided that an improper extraction is a non issue if it only happens with no mag in the gun, and it does not diminish my confidence in the handgun's reliability. My two cents.

Are you shooting winchester white box?

Smaller rim.  M&P has trouble grabbing.  Use other ammo and it should shoot fine.

With no mag and a loaded round is normal

I have 2 M&Ps, one of which has just over 10,000 rounds on it, that haven't had a stoppage of malfunction of any kind, however, when I eject a live round after removing the magazine the rounds will fall through the empty well.

I don't believe that represents a problem.

All of my pistols do this OP, polymer and 1911's... There is not a problem...

1911s should not do this if the extractor is tuned correctly

I think a little bit more tension on the extractor of the 1911 wouldnt hurt

Chamber a round, remove the mag, then fire the gun. How does it extract doing that?

Maybe, I think your probably right... However, I can't get this pistol to malfunction knock on wood. So I don't want to mess up a good thing. All my other 1911's I've owned in the past have done the same thing. All Springfields, all good pistols.

Haha, true! I bet it extracts just fine that way... I learned the hard way a long time ago that hand cycling rounds is NOT a good indicator of firearm function. It led me to believe a Browning Hi-Power was reliable when it was not and I was carrying it in that condition. I basically had a 1-2 shot pistol on hand. Shooting firearms under actual recoil is a good way to check reliability though. I'll never carry another pistol without shooting 500-600 trouble free rounds with mixed ball & SD ammo thru it...
