AFAIK, Mark I/II/III pins are identical. They are also a viable replacement for a broken Mark IV firing pin.

These are not in stock but are available for back order from Brownells.

That's very strange. Did they say why not?

Ruger sold me new firing pins for my MKII, MKIII, and MKIV. All they needed was the serial number for each one to sell them to me.

I think the OP got the stock Mark I answer: Ruger is not supporting them any more. The fact that, AFAIK, the firing pin is identical to the Mark II and III firing pins is irrelevant. Brownells doesn't ask for a serial number:



Unfortunately, not in stock, but it can be backordered.

BTW, I'm not hoarding (I keep telling my wife), but I did forget I had a couple of backorders pending.

Ruger wanted me to ship them the gun. No reason was given why parts could not be sent.

I placed a back order a week ago for 2 firing pins & a spring from Brownells. No email, or reply from Brownells.

This is not a drop in part. That is why River wanted to install it. You need to check that it doesn't exceed the proper length and end up putting a dent in the chamber rim

I will check fit . I ordered 2 firing pin. I may change the tip on one or the original pin.

Photos - Post 23. https://www.thehighroad.org/index.ph...s-okay.855107/

I already modified the orginial pin for more travel, without hitting the barrel face.

Ordered a main spring also. Not easy to replace, but did it before. I dont think the spring gets weak over time.

The new factory Ruger firing pin came in today from gunpartscorp. Edit: NOT Ruger.

The pin is not a drop in item. The firing pin protrusion is very short. Barely made a mark on the empty fired brass.

The nose area of the pin is also tiny. Make a dimple on the brass.

Not even going to test fire with the new pin.

My orginial pin has been modified and provides more protrusion then the new pin and has been working ok.

Will use other parts in photo for now.

May replace the main spring later?

I did modify the new pin to give it the correct amount of protrusion.
Of 50 rounds , 21 didnt fire. All fired on the 2nd try. The tip of the pin is under size.
Waste of $ on this one.
The oal of the new pin is shorter, adding to the problem.

Not sure if new pin is of Ruger manufacture?


The old orginal pin i modified , had 1 misfire out of 50.

How did you modify it? Did you weld additional material to lengthen it, or cut the hole longer to allow more travel? Something else?

Making the tip of the pin smaller concentrates the energy it has into a smaller area, resulting in deeper strikes. But at least now we know what you're trying to accomplish with replacing the FP. You're suffering from excessive FTFires - even with your old pin.

Can you post the OAL of your old and new pins please? Every pin I've seen from Ruger and the aftermarket vendors are all the same length.

These new Ruger pins work fine for thousands of people. I don't think your problem is being caused by your firing pin at all. Most likely, your chamber has a bad case of carbon ring or maybe your main spring has gotten weak. It's also possible that your bolt has excessive head space.

Have you measured your head space? What is the protrusion length of a new, unmodified pin? Have you tried borrowing a main spring from another pistol that doesn't have problems crushing rims? Can you post a pic of the hit on a failed-to-fire round?

I wasn't sure from your earlier post if you were trying to improve accuracy, or reliability. Please help us to help you here.

The firing pin in above photo are NOT Ruger manufacture. An email from gunparts corp said
Quote:
the firing pins are a new reproduction , aftermarket .
The aftermarket pins oal are 1.870" & 1.871" The protrusion is on the short side, almost not making contact with the ammo rim as they came new. The pin tip that makes contact with the round is undersize.

My old original pin oal is 1.875" with good protrusion and a pin tip with more striking area. Its been modified for protrusion & the tip height trimmed to not contact the solid part of the case rim.

The short answer is, avoid buying the Reproduction pin.

The Volquartsen pin and all the Ruger pins I have gotten were all 1.875" OAL. I haven't gotten any from Tandemkross or Majestic Arms, but they should all be made to match the Ruger OEM part spec.

I don't know who made the pins you got from gunpartscorp, but TK is the only one I know of that narrows down the tip like Ruger has done to their MKIV pins.

Still, your original (modified) pin that you said "has been working ok" is producing a 1/50 failure rate. That tells me you have another problem you need to address. A more normal failure rate (depending on ammo) is 1/500 to 1/1000.

My MKII originally had a 1/20 failure rate and I found the headspace was well above SAAMI spec. Once that problem was corrected, the failures dropped into the normal range. Your problem may be the same, or different. But it's not going to get much better until you investigate and find the source.

The old original pin i modified , had 1 misfire out of 50. When bullet was pulled to look at the priming compound, it was not normal.

I will check headspace, but i dont see it changing on a Ruger MK1. Its not a Mossberg bolt action rifle.
