Firing pin for Springfield 9mm 1911?

[MrChicken]

I researched and the consensus is to use the Ed Brown .075 pin for .38/9mm.
Part number 826.
I ordered one and it doesnt fit the slide. The factory Ti pin measures .071, the EB .075. The EB FP wont go into the FP hole. It fits the channel just fine, but the tip wont go into the hole in the breechface from either direction any further than just a smidgen.
To add to my puzzlement, I have a second Springfield 1911-A1 in 9mm and the EB FP works in that gun. One of them was made in 2001 and the other is more recent (guessing 2005, the year that I bought it). Is this a matter of needing a different pin, or of Springfield drilling different size holes and I need to get the slide re-drilled???
Is sanding the FP a couple of thousandths a no-no?

All of the newer springfields have a titanium firing pin the switch was made so they could pass the CA drop test without using some type of firing pin blocking device (schwarz or series 80), its smaller and lighter as you have found out. I have never heard of one of these failing, why do you want to change it????

My milspec has one it works everytime reliably setting off every round I have fired in that gun.

IMHO if you use another firing pin that does not fit the gun you are asking for trouble.

I replaced the ILS with a S&A magwell. I'd like to avoid using a 28-30lb mainspring for two reasons, to lighten the trigger pull and to make thumb cocking easier for dry fire practice.

Give George Smith at EGW a call..he can set you up with the right size firing pin..

Thanks!
Got a couple of pins on the way from EGW. Going to try the .073 and if necessary, the .068.

Not exactly Mil-Spec is it? Amazing how companies will take a proven design and tinker with it. I understand the need to pass the Cali test but, in doing so, the gun is no longer Mil-Spec is it?

Didn't Springfield always use an off size Firing Pin? I've never changed mine and it's well over 20K in the last 10 years.

Got the EGW firing pins

in yesterday. They fit !!!
The .073 pins fit both guns and according to my pencil test, will hit primers as hard with a 19.5lb mainspring as the original Ti pin did with a 28lb mainspring.


Thanks again for the help...
