Sig mainspring colors: is there a guide?

December 23, 2019, 11:52 PM

Hey all-

I am in possession of some Sig mainsprings that I wish to identify. Some are yellow. Some are black.
Is there list somewhere that decodes them?

Thanks,

Bruce

"The designer of the gun had clearly not been instructed to beat about the bush. 'Make it evil,' he'd been told. 'Make it totally clear that this gun has a right end and a wrong end. Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all. -Mencken

I’m traveling right now, but somewhere on the home computer I have saved the information that Sigfreund posted on this.

It may be in the tread on service intervals as well. I’ll see if Ican find it.

Love Top Gun Supply!

Don’t love the search function on their website.

Shop Gun Parts, then Sig Sauer Gun parts, then shop by category, then recoil springs.

Blue is P229 & 250C in .40S&W
Green is P220/P227 .45, P226 .357&.40, P250FS in .40
White is P229 9mm and M11-A1
Orange is P226 9mm and P250 FS 9mm.
Orange flat wire is P238.

Hope this helps.

Thanks. I did find the list of recoil springs, with the colors. Not what I was looking for.
I also found the mainsprings, but no colors other than red.

These are the only SIG factory mainspring colors I have seen:

Black, short spring: standard mainspring used in most of the Classic line pistols, P220, P226, P228, P229, P245.

Red: DAK mainspring used in P220, P226, P229. When used in a DA/SA gun it produces a heavier pull weight than the standard spring.

Yellow: a rare, now-discontinued spring rated at 18 pounds by the factory. Long ago I ran across a couple of references that indicated it may have been used in double action only pistols for a time. If true, it was probably because the lower power of the spring made for a lighter DA trigger pull and the extra power wasn’t needed to keep the single action pull weight from being too light. When I used a yellow spring in a DAO P229, I experienced light strike misfires.

Concur, I must love top gun supply given all the spare parts I have from them, but truly hate their search facility on the web site. Is an odd site anyway not quite like any other. What generation of web sites are we up to anyway? I have lost track since retiring couple years ago
