Replace firing pin on MIM Smiths?

[RevLoverJim]

The firing pin on my new 629 Classic appears to be a bit more pointed and have a bit less protrusion than the pins on my older Smiths.

Do any of you have experience with replacing the firing pin on the MIM Smiths?

Thanks,
Jim

I'm pretty sure the engineers at S&W have some experience with them.

I'm also pretty sure that the company with a lifeline warranty is confident in them.

What makes you think that the first iteration is the better one and not the second?

If it pops the primer every time, why worry about it?

Hate to say so but you bought it knowing what you were getting.

I have no sympathy.

Welcome to the forum.
I have not replaced a firing pin on any of my in frame guns because they all work fine. They don't seam to break any more often than the hammer mounted ones. If its working I would leave it alone, if not, somebody in the gunsmiths section may know how to proceed.

Some people can't stand the newer guns. There are some things about the older guns to appreciated, but, that is not what is new on the shelf today. In most respects the recent guns are fine and if I really really didn't want anything at all to do with them. I wouldn't be reading in this section of the forum.

Cylinder & Slide use to make replacement firing pins for the post 2001 production revolvers. Dont know if they still do. Good luck!

Apex makes an aftermarket floating firing pins for later model S&Ws w/ different weight springs depending on the application. Also believe there's a couple other companies that make aftermarket firing pins that are a tad longer than factory to help ignition. It's pretty simple replacing the firing pin if needed and there's a you tube video if you google the subject.

If it works and not broken why replace.

Did you buy it to stare at the Firing pin or shoot it?

Thanks for the helpful reply

Hey, Jim. If you're comfortable with removing the side plate, the firing pin is simple to change out. It's held in by a floating pin that's captured between the side plate and the frame.

Let me elaborate a bit , yes it is easy to remove . all you need to remove the firing pin is a pair of tweezers and a toothpick . Remove the side plate , please use a gunsmith screwdriver and put your craftsman driver away . The 3 screws are a bit different so place them in an order on a white cloth so you will remember which screw went where . Remove the grip , lay the revolver on it's side on the palm of your hand and tap the grip frame with the handle of your screwdriver until the side plate pop out .
DO NOT PRY it off as you will bend it and it can't be straightened properly . Use the tweezers to remove the cross pin that holds the firing pin in place (it's at the top of where the side plate fits ) . Use the toothpick to remove the hair spring inside the recess for the firing pin . Now you can clean the firing pin and the recess , or change them out if you so desire . I have a 29-10 that misfired a lot , simply cleaning the firing pin and the recess cured my problem . After a while you get a buildup of crud on the firing pin and in the recess hole . I hope this helped you ,good luck

Thanks to all who replied with positive info.
I did see the vid on Youtube--so easy even a caveman can do it

Firing pin ordered from Cylinder & Slide.

Some think a longer frame mounted firing pin can improve ignition when lighter springs are used in the gun. I bought a J-frame reduced power spring kit once and it came with a new longer firing pin.

Smith & Wesson had a problem with under length firing pins a few years ago. I had to replace the one on my new Model 67-6 immediately after I purchased it. This was a common and known problem at the time. I used a Power Custom replacement firing pin to replace the factory version. The Power Custom firing pin was the proper length, as opposed to the factory firing pin which was too short by about three or four thousandths. All Smith & Wesson revolvers use the same firing pin in these models with the frame mounted pin, and Smith & Wesson got a bad batch from wherever they get them (either made themselves or by jobber). Since replacing the original firing pin, I've not had any problems, firing many thousands of rounds through the Model 67. To clarify, I was having light primer strikes when the gun was new, but none since I replaced the firing pins.........

My new 625PC's firing pin was more pointed than the older ones too. I had bought an Apex firing pin several years ago expecting I'd need it for one of my Night Guards (stories of light strikes) but never needed it.

Since the Apex had the more rounded nose I installed it in the 625PC, while I had the side plate off to add a lighter rebound spring, just for the heck of it. The factory was .490" long & the Apex measured .500" long. That rounded nose firing pin really puts a wide crater in the primers (factory mainspring). Needless to say, I've had no issues igniting primers with it.

I ordered a replacement firing pin from Apex to have on hand, just in case. Wouldn't you know it, the new one (.496" long) I received has the pointed nose, like the factory.

Hopefully the C&S firing pin you get will be rounded.

Hmmm, you have nearly 2,000 posts and one would expect you've had years of experience with Smiths. The OP is on his
fourth post and probably doesn't know a lot of Smith history.
And his question doesn't indicate a lot of knowledge about what makes a Smith go bang.

You sure told him!!!!!!!!!!

APEX and C&S firing pins

I ordered a replacement firing pin from Apex to have on hand, just in case. Wouldn't you know it, the new one (.496" long) I received has the pointed nose, like the factory.

Hopefully the C&S firing pin you get will be rounded.

Follow-up: I emailed Apex twice trying to find out why the change, or if I got the wrong part. Never got an answer for it.

Since I posted this I've bought a 325 Thunder Ranch, & a 327TRR8, & found they both had light strikes/FTF with their .486" firing pins. Put the new pointed Apex F/P in the 325TR & it worked but with some very light strikes, no FTF. Put the older round nose Apex F/P in it & it worked great consistently with broad deep impacts.

Just received the C&S extra length firing pins (CS0188) I ordered from MidwayUSA (since Apex wasn't helpful) & they are .510" OAL & have the broad rounded nose. I also bought a factory S&W F/P from them, just for grins, & it measures .497" OAL with a broad round nose.

Sure wish S&W would go thru their parts bin & throw out all the .486" F/Ps & stop installing them in new guns.

My gun smith tells me the "updated" firing pins are slightly longer on both sides than are the original stock pins due to inconsistent ignition with some guns some times. Mine so far has given me zero problem so I have no plans to replace it.

 

[ltj9296]

interesting subject. Even though I have had a S&W model 10 for about 30 years, I have only recently starting to learn more about revolvers. I have been thinking of picking up a less expensive k or L frame and attempt to to smooth and lighten the trigger pull to about 9 lbs. Mostly as a learning experience. I will pay close attention to the firing pin when I do so, and replace if needed. I am concerned if I lighten the pull, I my have problems. Good information here, thanks everyone!
