Springfield ILS...msh replacement question

[alland]

.068 normally fits Colt and Caspian 9mm/.38 Super/.40/10mm. .075 fits Springfield Armory 9mm/.38 Super/10mm/current-production .45 ACP. .093 fits most .45 ACP, including older-production Springfield.

I recommend that the existing firing pin be measured. Things are not that easy now. The .075 firing pin that I bought for my 9mm Range Officer would not fit. I measured my titanium firing pin and discovered that Springfield is using .068 firing pins now, at least in mine. My Range Officer is about 6 months old.

I ran a 21# mainspring, 17# recoil spring and XP FPS in my MC Operator without any issues of light strikes with a variety of different kinds of ammo and primers. I recently switched to a #23 mainspring and will switch to a correct-sized steel firing pin and I dont expect to experience any issues.

If the Ti FP is reliable enough providing consistent ignition then it's all good. With my experience an extended steel FP gives me better accuracy with certain types of reloads.

I measured and weight the firing pins in my 1995 SA Mil Spec 1911 and 2016 SA Mil Spec 1911.

1995 - Steel FP / .0710" diameter at tip / 67 grains

2016 - Titanium FP / .0715" diameter at tip / 37 grains

I don't understand the outfits offering a .0750" or .0650" for an SA 1911. If I was going to get a steel FP for one of my SA 1911 pistols, I would call the fellows at Wilson Combat (nice guys) and have them send me one that's at the large end of their range which I believe is .0685" - .0695". Who knows, they might find one that's .0700" or .0710". Good luck.

I used an Ed Brown 9mm firing pin and an Ed Brown extra power firing pin spring which is still less than Springfield standard in a CA model.

Edit**I need to get a new msh cap since the above post got me worried about extra pressure from the stock Springer cap being larger. I mean it works fine and all but still**

The msh cap is normal I just checked**

But I have never measured their FP so I don't know for sure.

Thank y'all for the replies! This helps.

QUESTION!
What in heck tool would I buy to measure a firing pin?!

[threeperreaper]

Why? What do you hope to gain with a steel firing pin?

Hey it's your gun and money, do what you want. But since you're here asking questions, I'm just wondering what your goal is.

Deleting ILS, lighter springs I get, they change the feel. But changing the firing pin does nothing. Just wondering why it's on your list of things to do.

In any event, have fun with it.

Others have stated that it (apparently) would help give heavier hammer strikes...yet state it may decrease its drop safe-ness (<---not a word, I know)

I have no issues with the titanium one...just want to dry something different

Honestly, I'm only doing this because I enjoy the tinkering and testing...which is why I bought a 1911 in the first place (I've done the same with polymer guns, trucks and motorcycles)

I'll eventually change out every part and someday hope to build one from a Caspian an slide/frame after I've made a bunch of mistakes on the ones I have now..

Just asking a few questions so I don't waste TOO much money on parts that don't work in he first place

You'll need a dial caliper, unless you really want to get precise measurement with a micrometer.

^^^This, if you need to measure it.

You could always take it out, then put it back in. Same effect as actually changing it, but you keep $10.00 in your pocket. It's one of the only small parts (ejector, extractor and some pins being the others) I didn't change out in my Springfield gun. Springfield quality is sooo hit and miss.

Hey, you never know... enough people say it and voila, it is a word.

Look up irregardless, disenheartening, etc...

Best post of the thread. Congratulations Sir, you win the internet today.

All of my Springfield Armory .45 1911s have been 0.075 firing pin diameter, and 9mm ones have been 0.065 Btw. But you should measure yours before ordering one online.

[Geologist]

Just to reiterate what FreeCalifornia said, I asked SA this very question about my Loaded Target (45ACP) last week. Here was their answer:

The recoil spring is 16 pounds, the mainspring is 23 pounds.
Mainspring with ILS is 28 pounds.
We just use WolfXX power firing pin springs.

[MosinVirus]

Take this part for what it is, most people are so afraid to run less than stock weight recoil springs but it really doesn't fuk'in hurt a thing. All the good shooters I have seen run 14# recoil springs or less without ever "causing frame damage".

It sounds like you know what you are talking about, so I have questions. Wouldn't going low on both recoil and main springs change the timing and increase the risk of parts damage?

From frequently visiting other 1911 forums it is clear that changing the power of one or both springs changes the speed of the slide. Are you saying there is no effect on parts when they slam against each other with more force?

Basically frame/slide/barrel battering is a myth?
