Glad to hear you attempted it!
I always feel more connected to a weapon that I know inside & out.

I completely agree. I absolutely love doing my own work and hate when I can't.

I can't begin to describe the satisfaction I get, when I have one of my guns down to bare metal/frame/etc do my own polishing/trigger job/etc and reassembling.

I have taken the FCU completely down and back together, no problem at all.

I am stuck on the firing pin pin.

I cannot figure out what you could have used to get that pin out.

I have a 1/32 punch that looks and feels too big and have not wanted to do any damage with. That's the smallest punch I have (and in fact seen) and smallest drill bit I have.

Can you (or anyone else) show me what and how you used?

Thanks,

Doc

The firing pin pin? Do you mean that first roll pin which begins the disassembly procedure?

Sig sells a P250 tool kit that has the punch you seek.
http://store.sigsauer.co...armorers-punch-set.html
also the spare parts kit comes with a new roll pin.

Thanks for the tutorial. It is excellent.

Yeah, I saw that tool and thats pretty steep price. Especially with the other one not needed at all... a 3/32 punch held the springs down perfectly for the pin to start its way in.

GrumpyBiker didn't use it and even said a drill bit could be used.

So I want to know what size he used and where he found it etc

Don't be. It's a good resource. Especially the spare parts kit for later on.

And it would be a great if I had the 25 plus shipping to spend on a specialty item like that.

But it is a whole box of ammo or another 25 towards this 1911 I have been coveting Love

Ok all done.

Made my own "punch"

Took a 78cent comedone extractor that daughter never used, blunted the sharp point,

knocked the pin until the taper didn't let it go any further, marked where that was, and filed about 3/4 inch above that down to that marked thickness.

Then pin came right out.

Cost: 78 cents and 10 minutes with a file Cool

A set of roll pin punches are pretty cheap and will keep you from damaging the pin.
You're correct, I didn't use one in the photos.
I was lazy & didn't want to stop to go into my safe where I'd left it & I thought folks would be attempting this without any real gunsmithing tools.
Sorry, I hadn't checked in here for a little bit.
I've been budding ARs for folks lately.



Huh, this appears to be post 2700 for me !Laugh

Hi, Grumpy.

The problem with the punches was that so little of the pin was exposed on the slide underside, that I didn't have anything small enough.

No punch I had came near.

That is why I was wanting to know what you used.

Then I MacGyvered up a punch.

BTW, what did you use? and what size?

I made a punch from a broken bit, it's 2.35mm in diameter, I beveled the side to fit through the hole better.



I hope that helps.
Have fun.

I went ahead and made one myself , also made a hammer spring tool...



facial tool that I filed and dulled : 78 cents

aluminum crossbow pistol bolt filed and wrapped with skateboard grip tape : 15 cents

time : 5 HOURS LOL

I know crazy spending that long MacGyvering something readyably obtained for $20, but I gotta tell ya, I would have gladly spent 12+ hours making it myself Cool

Much needed post. I have two slides I'm upgrading to night sights. Obviously, you need to know this procedure to do that.
