M&P 9 Pro Is Back From S&W

Aha!!  My M&P will now eject brass without pissing me off!  Similar to my 1911, except for the vigor of the throw, the brass is going out at around 4 to 5 o'clock, rather than 5 to 7 o'clock like it was doing before.

A note that followed the pistol home read:

REPAIRED: BARREL MODIFICATION

REPAIRED: REPLACE EXTRACTOR

REPAIRED: INSPECTED/TESTED & PASSED

I'm not sure what they did with the barrel.  It looks the same to me, with no obvious signs of modification.

I did have one rather odd malfunction while testing it after I got it back.  I pulled, and pulled, and pulled on the trigger, and it didn't fire.  The striker wasn't cocked?  I went to rack the slide and it was sticky, but with a sharp tug I got the round out of the chamber.  I loaded the round back into the mag, and continued shooting until the pistol was empty.  I didn't think to look at the round that it hung up on.  Hopefully there was just a burr on the brass casing that was holding the slide out of battery, keeping it from firing.  I dunno.  If it happens again, I'll note it.

Reading through the Pistol-Training.com blog's M&P torture test posts, it looks like Todd had a similar problem, with the trigger not resetting.  Weird.

I plan on taking a couple carbines out next time I go shooting, so it may be almost a month before I get to shoot the M&P again.  I have an LMT upper that didn't pass with a headspace GO gage, but seems to work with a carbine buffer, if not the "H" buffer.  The tech guy at LMT said the headspace is supposed to be tight, although it seems strange that it wouldn't pass with the GO gage.  I dunno, I'll have to see if it breaks in a bit or just functions anyway.
