PC firing pin replacement

[TwoPoundPull]

I need to replace the in frame firing pin on an N frame.
Mod 627-PC SN LHVxxxx
The firing pin retaining pin is installed from the top, under the rear sight.
No provisions for pushing it out under the side cover, and is set slightly below the top.
Thanks, 2#

You simply remove the sideplate and lift it from it's hole with tweezers or small needle nose pliers. The firing pin (and spring) is then free to slide out the back. You then slide the new parts into the hole, making sure to orient the flat on the firing pin towards the retaining pin, drop the pin in the hole and replace the sideplate. Super easy.

OK, you said installed from the top. I haven't seen that kind. Maybe you can take off the rear sight and dump it out?

Interesting! I went to check the firing pin length on my 627PC the other day and could not determine how the firing pin was installed. I did not think to pull the rear sight assembly off! I was just interested in measuring it, so did not worry too much about it, just checked another gun.

Frame mounted firing pin removal

Okay, you guys are messing with my head. I don't know if I'm misunderstanding you or S&W makes something I've never seen before & is not like any other model?

If you remove the sideplate & pull out this pin (red arrow below) your frame mounted firing pin can be removed.

Do you have something different? If so, pictures are required.

Firing pin retaining pin set in blind hole under adjustable rear sight.
Hope this helps.

My guess on that would be turn the gun upside down and depress the firing pin and it should fall out. If not, maybe it has some dirt or rust in there. Never seen that before. Maybe it's one of the first firing pin in frame guns?

Never noticed a hole like that before but the rear sights aren't removed very often either.

What makes you think that's for the firing pin?

Have you actually removed the sideplate on your revolver to see if it does have a retaining pin for the firing pin like in my picture?

Please believe me when I say this is not my first rodeo, I am usually able to repair what few failures I've had with N, L, or K frames.
(Don't own any J's)
This issue is entirely my doing, I use this weighted bbl N frame for steel knockdown. My steel loads are somewhat "warm".
Switched primers, some ended up piercing, I flame cut the firing pin and would not retract, locking up the cylinder.
The first thing done was remove the side cover, as the retaining pin was not where it was suppose to be did I look under the sight.
Called S&W, asked to speak to service, was politely told they can not put my call through to warranty and repair, but will send me the parts when back in stock.
In all fairness, I was told to send the gun in and would be repaired, I felt it a little extreme for a firing pin replacement.
If I were looking to swap out a bbl or fit a cylinder it would be a no brainer, but not a firing pin.

TPP,

The experience you're having with your firing pin retaining pin, seemingly led to the new style with pin under the sideplate.

I would do as Protocall suggests but also spray a little WD-40 in the hole while the gun is upside down and tap the side of the gun with wood screwdriver handle or the like. While also manipulating the firing pin as he suggested.

You can also use a magnet with gun upside down; SS used on guns will be attracted by a magnet.

And as you likely know, flush out the WD-40 to keep the pin from sticking next time, and don't use it anywhere else on the gun.

Mod 627-PC SN LHVxxxx. The firing pin retaining pin is installed from the top, under the rear sight.

I don't see this prefix listed in the SCSW. Do you know what year this revolver was made?

Seemingly? Has anyone else every encountered this style before? Was this a prototype revolver?

S&W made this revolver for Lew Horton in Feb of 1998.
One of 338 distributed.

I would do what Jim (Hondo44) tells you to do, but would substitute Kroil instead of WD40. I don't let WD40 anywhere near any of my guns, (unless I might someday drop one in the water). I would have never found that retaining pin under the sight, and would have been on the phone to S&W. What dash # is this revolver? Is this method still in use?

 

[TwoPoundPull]

I don't believe I own any WD-40, but I am a fan of Break Free CLP.

The model number is.....627 (dash) PC

Got it out, put a drop of Xylene on top of the retaining pin and let it seep in and around, cable tied the trigger back, shimmed the hammer to center the firing pin in its travel, used an air gun with a rubber tip and with just shy of 150 psi air pressure, blew into the firing pin bushing and shot the retaining pin out of the frame.

Xylene is a thinner/cleaner similar to Methyl Ethyl Ketone (MEK)
But it's not suppose to kill you.

Great thread! I have one of the 627-PC revolvers in my safe. I don't shoot it much because it's probably collectible. Now I must get it out and inspect.
