extended firing pin for 686?

What would be the advantage of an extended firing pin. Would I then be able to have a lighter trigger (for IDPA). I see there is a tradeoff...with factory ammo you need a little heavier trigger. Maybe the longer firing pin would help with this?
thanks in advance

I don't believe a longer firing pin would give any advantage in the trigger pull.
I have Cylinder & Slide forged firing pins on the way to replace the MIM pins in my two S&Ws that have them. These new pins are also slightly longer, but the two advantages that I understand are in what I regard as a better material, and in addressing what C&S tells me is a recent change in headspacing on S&W revolvers.
For more info you might email C&S at their website.

I've installed several C&S extended firing pins in my S&W revolvers. They allow you to use a reduced power mainspring, and still have 100% ignition. Nice product.

Good Luck...

Joe

OK, I am wondering? If one installs WolFF springs then you should install the C&S extended firing pin also? It seems odd that you have to buy from two different suppliers. I buy the headspace explanation. I am not certain that installing a extended firing pin IS the solution for weak springs. I do strongly support MIM elimination!

OK. What still concerns me is that S&W has not admitted they have a problem. WHY adjust the heaspace? WHY install heavy springs in your revolvers with 12+ lbs pulls? WHY are people complaining about S&W quality? I see S&W products as "starting points" today. They cannot be left stock for reliability, durability or trusted with your life, out of the box.

JoeHatley's use of long firing pins agrees with what I have heard and seen.

Jerry Moran was putting long firing pins in Pythons with light mainsprings and other DA pull-reducing mods so as to insure ignition reliablity 30 years ago.

The factory is not always right, but they have to leave ample safety margin for the rough guns they are turning out and the junk ammo readily available on the market. Somebody who knows what he is up to can do better.

I was mistaken..Wolff does not have the long pins..I was thinking of C&S.

BTW, SW tirggers remind me of Martin Guitars that come from the factory with the strings up high off the fredboard making them hard to play...many people get them adjusted after they buy them.This adjustment is called lowering the "action"

I installed the C+S extended pins in my four comp SW guns and I did not see any improvement in the minimum mainspring force I needed to get suitable ignition force. The C+S pins are also poorly made and every one had to be fitted (they are too long when new, and two of them had casting flash that bound up in the channel). I am underwhelmed in general with the extended firing pins, but I think the Wolff ribbed mainsprings are first rate. They give a reduction of about one pound in DA pull compared to a "dialed back" stock mainspring (shortened strain screw) when both are set up for the same striking force.

For the record, the C+S "extended" pin only goes out as far as all the old smith firing pins which are mounted on the hammers. So it is not accurate to say the C+S pins are "extended", it would be more accurate to say the frame-mounted stock SW pins are UNDERSIZED.

Hi Bounty,
I just got two C&S pins today in the mail, they look perfectly formed to me.
I expect them to have to be fitted, I think that's the whole point in having them made extra long.
Maybe the "extended" C&S pins & the "undersized" current factory pins are all relative? Maybe by extended, C&S just means extended longer than current factory pins, not necessarily with more protrusion than the older hammer nose firing pins.
Possibly just a different way of saying the same thing you're saying.
I have two Smiths with MIM pins, the C&S pins are to replace them, so even if the length isn't a critical issue, or the mainspring tension, the choice of pin materials remains an important one for me.
