Extractor removal issues on M&P

Howdy, first post on this forum.

I just bought a very nice one owner M&P Pro from a friend. Shot it a few times, runs great, love the gun.

I wanted to do a detailed tear down (extractor and firing pin) and cleaning so I looked at a Youtube video. Long story short, the firing pin was no issue, but I busted a 1/16" punch trying to drive out the pin the extractor. No clue why, in the video, the guy drives the pin out with a normal amount of effort. Mine is welded in there apparently?

Any ideas? Thanks.

I was having some issues on one of my M&P's, as part of the investigation I took the extractor out to check for any debris that might be messing with the extraction. Best I recall it came out easily with the right size punch, if the punch is a little too big you can pound on it till the cows come home and it won't move, I found this out by personal experience. I thought it was the right size punch but that pin wouldn't budge, went to a smaller punch and it came out easily. What looked like the correct size wouldn't fit in the hole when I checked it with the pin removed.

Quite frankly you really shouldn't need to remove the extractor as long as it moves relatively freely within normal limits.

What John said.

And by using a smaller diameter punch, it will hit the center of the pin and help move the pin easier because the very center of the pin will move first, then the outter surface of the pin will release its grip. These pins are NOT solid pins, they are more of a expansion pin. Collapsing (so to speak) the center of the pin is how you get them moving by hard smooth hits. You should spray it with a good lubricant (something like KROIL) and let it sit over night, then try to remove the pin the next day. This method has NEVER failed me in 50yrs of gunsmithing.

If you have one of the older ones with a solid extractor pin, it can be a bear to get out (and back in).

I've done one, and when I got the extractor out, it was basically clean in there (the design actually keeps things clean). That was after seven years of shooting.

If you just have to take yours out, I removed the solid extractor pin (punch goes in the top to drive the extractor out the bottom) by using a steel nail set punch. I drove it down until the punch was too big in diameter, removed the punch, grind down the punch a little, then go again.

If you start with the correct size punch, it'll just break off.

Also, at the time I did mine, I was advised on this forum that the solid pin is tapered, hence the need to drive it out from top to bottom of slide.

If you do remove it; replace it with a spiral pin.

I don't plan on doing it to any of my M&P's again, as it really was clean in there, so no need to do it.

In the Youtube video, the guy said he used a 1/16" punch and that's what I used.

Well, if it's working, I will leave it based on "7 years of shooting" statement. I am hoping that 7 years is more than "Put a box through it every year" because I shoot a lot more.

I cleaned my STI Trojan 1911 at the same time, it had maybe 1000 rounds since the last cleaning, it was like a toxic waste dump in there.

Thank you!

As mentioned above, early series M&P's used a solid roll pin; later models a spiral roll pin - both 5/64" diameter.




You generally will need to sequence the procedure, using a tapered style "starter" punch to get the initial movement of the solid pin then complete the task with a parallel pin punch;



If you don't have a tapered starter punch use a short-shaft hardened pin punch.



If a roll pin is present, use stepped length roll pin punches for the same reasons, or you can bend the shaft just as easily.



Regardless of pin style, they are both uniform in diameter i.e. not tapered.....if you examine them closely the ends exhibit a slight chamfer edge to facilitate their initial entry into the hole, especially if using a hydraulic arbor.



Remove them in the direction of top-to-undersurface of the slide; upon replacement, install from above and check to make sure the pin is not protruding in the rail recess.

Wow. Outstanding, detail overload.

At least it proved that I'm not a moron (in this particular instance, mind you) for struggling with it.

Thank you very much!

Well Sir, I shoot two (used to be four) IDPA practices a month, plus a monthly match.

I also attend at least two training courses per year, and those are 1500 round count weekend courses.

So I'd say I'm a ways beyond the "one box per year" crowd.

Also, being a long time 1911 guy myself; I can say that the extractor on the M&P is a completely different animal than the internal 1911 extractor, with that long extractor channel just waiting to get loaded with fouling.

I stand corrected, i`ve never seen (or worked on) a shield that had solid pins.

Solid pins probably never were installed on the Shield series as they are relatively new

I am pretty sure the one of mine that I pulled the extractor has a solid pin, its a Pro Series made in 2015.

OK, I stand corrected, the M&P Pro I pulled the extractor on has a roll pin, my M&P40 has a solid pin, it was made about 2006, and my Shield (not shown) has a roll pin.

Well Pa, I'm pretty sure you're right about the Shields, as they're a fairly recent addition to the M&P line.

The OP's pistol is a used Pro model.
