Looking at the pistol, it looks like the extactor retaining pin in just a strait pin, with the hole strait through the slide (top to bottom)



So what keeps the extractor retaining pin from coming out of the slide when you're shooting, other than a really tight fit
?



Thanks guys.

Properly designed pins will have a press fit that can not be vibrated loose over time. The pin does not move at all during swervice so there will be no wear issues and such will remain in place for a LOOOOOOOONg time. Unless you remove and replace it a lot youre not going to see any wear on it. The MP also has the melonite processing done with the pin and extractor inoplace, so you ave yet another mechanism keeping it there.

Well damn, what if you need to replace your extractor, makes it a lady don't it?

I think a follow-up question would be...how do you remove the Extractor without damaging the slide or the Melonite finish? Pounding on a new gun with a hammer doesn't seem the right thing to do.

Yeah, it almost seems like the engineers dropped the ball on this one.



The extracter is a vital part that needs to be removed, inspected, replaced if needed, on a regular basis.



Giving a "retaining pin" a press fit is a little stupid IMHO. Why not just weld the lady on while your at it.

Wasnt agreeing with the exact execution of the design, just stating the fact that a properly designed pin will not fall out under normal use. I havent tried to take the pin out, so I cant comment on the execution, but it does seem like its a bit over done. On the good side, I have never once had to replace or remove an external extractor from any of my non 1911 type guns. Maybe SW feels that its not a routine maintenance item, so they didnt care if it took a press to get it back out, so long as it didnt fall out ever... Just giving them the benefit of the doubt.

I understand the pin is pressed by a hydraulic ram. Rumor has it that it's almost impossible to remove without sending it back to Smith & Wesson.

--Proceed at your own risk.--

Make a short starter punch.

Lay the slide on a protected hard surface with the muzzle hanging off the side, so that it lays flat.

Use a large hammer and the starter punch to knock the pin loose, top to bottom.

Once it breaks loose, it will punch out fairly easily.

--Proceed at your own risk.--



The slide is Melonited with the extractor and pin in place. This makes it very hard to break loose.

I have heard from a couple sources that S&W is thinking about using a roll pin here for easier disassembly. I don't know if this will happen, or not. At this point, S&W isn't even training armorers to remove the extractor.

Have fun!!!

Hey Olyeller it does work as Yukon described and it is easy to put back in you just have to be careful not to tear the slide up. When you put it back in use a slightly oversized punch to tap it back in. A heavy hammer works best for removal and once again care must be taken not to tear your slide up. I use Sterret punches because they are about the hardest punches out there...

I have actually done this. I used a 5/64 drill bit to make my starter punch.

What are you wanting to replace?
