Some microbe with just the right enzymes fortuitously happened to land on this most bountiful feast!

 

It only has a high temp range of 170* . Seems kinda low for being around a hot barrel .
Don't know why it turned green . There site offers zero info on it .
I have use a 2oz can of Pro-Shot products Pro-Gold grease for 20 years on bolts and slide rails and other heavy load/wear areas . I tinny bit goes a long way . Still half a container . Good from 0* to 500* but works well at minus 10 too .

 

It is strange indeed. The barrel is fine, left front slide is fine but everything else is green.

 

Do you normally run the gun with this much grease on it or is it for storage?

 

Does it smell rancid?

 

No it doesn't, it's a little harder, not by much, but harder, than the grease in it's normal white state.

That and I have pretty bad allergies with all the trees and plants... reproducing...

 

I would've thought that they were broken down by the local bugs, or undergone some other rancidification.

...really not sure...

 

I've seen so called "waterproof" grease get like that. Almost feels like soap. I used it for a bit on off road motorcycle suspension bearings. Specifically designed for that application. Then, after seeing the way it set up, I quit using it.

 

Actually, lithium is a soap IIRC.

This one kinda stumps me, too. I was going to say it had residue of Hoppe's or other bore solvent on it that carried jacket fouling from the bore to the greased area, but nah, that ain't it. Your grease is green all over.

Weird.

 

You need a better grease if you have to run that much. Go buy a tube of quality synthetic grease from red line , royal purple or amsoil or look for some of that Pro- Shot Pro Gold gun grease if you have to lay what you have been using on that thick .

 

Lubriplate 130-A concern.

Pretty simple solution. If you have a concern about what you're using/doing, stop using/doing it.

Doing the same thing over, and expecting a different result will never be satisfying.

For me, Slide Glide works. You may want to try it.

 

OP:

Try G96. Seriously.

 

Maybe some kind of copper reaction?

 

This is military grease. And they shoot, strip, clean and regrease almost daily. There are better greases. Go with a synthetic grease. I use any brand name synthetic axle/bearing grease preferably in a can. I shoot a lot of M1a and AR15/10 and stopped using Lubriplate years ago, when synthetics became popular ( early '80's ). I am using Valvoline now. Not because it's better. It was just available. If you shoot a lot, say 100 rounds a day, a can will only last about 30 years. I venture to guess if you buy a can when you turn 21, you can pass it down to your grand children.

 

That's way to much grease. A little rail wear is normal on Sigs, I've owned them since 1985. Don't freak out about it.

I'll get pic up of my P239/357 rails.

Just for clarification, Lubriplate 130A is beige...not white. Also, it is a calcium soap grease. Not lithium.

I'm wondering if it's a calcium soap grease, it's cleaning off any gunpowder I missed during cleaning. Is that possible?

 

I use Shooter's Choice. It's never changed color, same red color. If anything, it evaporates or something. I only use a thin coat on the barrel and rails. After two months I cleaned and at the time, the barrel was almost dry. I have a syringe I bought locally several years ago. It's almost used up. Never had a problem with it. You might like it.

 

Update*** I went to the range today, with both the sig and XD. I didn't want to, because I am on a budget after being laid off. I shot a number of rounds through it with clean lubriplate.

Both guns turned green, it's from the ammo. I shot Remington UMC, Perfecta and Federal Aluminum.
