I did a search here and it's apparant that I'm not the only victim of a fractured MIM firing pin.

Thanks to this forum I found a supplier of forged replacements, I can not understand how anyone could trust a replacement from S&W.

Are you talking about S&W revolvers? The firing pins in FMFP revolvers are titanium. The only firing pins that break are the C&S extended ones.

First I ever heard of a stock SW pin breaking. The C+S pins break like crazy.

Really? So what with a lighter MIM hammer combined with a lighter more brittle FMFP it appears S&W is intentionally building unreliable
revolvers..you were aware that titanium is far more brittle than tool steel?

So watcha give me for the only broken FMFP (your words tomcat)

Yep, read all about the C&S right here thanks!

Search is your friend bounty hunter.

At least you now know they're titanium not MIM (your words Ultima). No MIM bashing rights there. How brittle they are or aren't is a matter of heat treat. I did a serarch and couldn't find posts where the Ti pins were breaking. Just people feeling a need to replace them with extended pins and then wanting to know how to extract the broken (tool steel) extended pin. The "real steel" hammer mounted pins occaisionally break too.

Where did you find a forged firing pin for the S&W FMFP revolver? Who makes them?
 
I want to know were to get a Forged FMFP as well..
WERE??
Thanks

BTW I have a C&S extended FP in my 342Ti & it's been 100% since it's instaltion..

Would be iteresting to know. It's an unlikely part to make as a forging.

As for your C&S pin, some people have had them live ok. My 625-8 came with one of the "short" Ti pins. I went thru (broke) 2 or 3 extended pins before I could get one of the longer S&W Ti pins.
 
I have one of the Longer Ti pin in the stash..
Don't realy plan on buying any newer revolvers anyhow if you know what I mean..
I remember reading here at the forum of someone else that made Firing Pins & supposebly they were better than the Cylinder & Slide made ones.
There's several people who would like to know..
WERE?? Someone Plese Tell Us!!
Thanks

Randy Lee / Apex Tactical makes one.

H/K,
That's the one I recall Tomcatt referring to in the past...

I haven't used one of the Apex Tactical firing pins. I'm using the S&W Ti pins, but the Apex are the only ones I'm aware of other than C&S. The Apex pin also includes a firing pin spring.

Of course we're waiting to hear Ultima got a forged firing pin.
 
Send Randy an E-mail. He is very busy so it may take a little time but once he has the firing pins in stock you will be on his list.

I have one in each of my revolvers. No problems at all.

???

Why would I search when I am one of the people who have posted that the C+S pins break.

I thought you had a different source which was breaking since the C+S failures are well established information.

Spoke with Randy a bit ago, busy guy!

He sub-contracts the firing pin from a stainless (17-4?), yes gentlemen the S&W pin is MIM a MIM blend of titanium and god only knows what else. Check Brownells, they say MIM also.

Having seen multiple titanium firing pin failures in Glocks/1911s and various aftermarket Remington 700s the entire concept of titanium in a weapons ignition system is redickulous.

Forgot to write down the firing pin/spring unit cost, $29.95 shippeed???

I didn't know the C+S pins were forged? I recall having to file the "flask marks" off them which were dragging in the firing pin channel so I thought they were either cast or MIM, but maybe they are forged and badly machined.

I thought everybody already knew that all the small piece parts on newer SW's were MIM. That's not news. For the record, MIM parts are not necessarily inferiror to forged if they are made right, but I thought that topic had already been beaten to death.

I was told the C&S "extended" pins were 4140 and I assumed were made from bar stock. I've been wrong before.

I wouldn't take Brownell's part description as the last word. My official S&W parts book shows a MIM FMFP # that's listed as obsolete then a FMFP (current) that DOES NOT say MIM. Who knows, they are decidedly lighter than the C&S and are definitely non-magnetic. The S&W firing pins seem fine as long as they're the .492" (or longer) ones. There were some that were shorter (low .480's) and could be an issue. So much for flogging dead horses.
