Many new P frame sigs over the years. Always came with TW25 grease. And I used it. Read Florks input.
THEN they started to come with that Lucas oil. Tried it, not impressed.
New 320 X5 Legion came. Wow! Instead of being dipped in oil, it had grease! SPEC1, which I see is basically Slip 2000 oil/grease.
Sound decision.

Despite claims of superiority, most lubes are as good as the other. I've tried most over the years and never noticed much of a differrence.

Sig probably uses what's cheapest or gives them a better sponsorship.

Both grease and oil have their place on guns. It's not either/or.

Oil is better for short term external protection for guns that are in use, and lubrication of small/tight areas.

Grease is better for long term external protection for guns in storage, and lubrication of larger/open areas.

The general rule is that if it's a sliding surface, use grease.

If it's a rotating surface, use oil.

There is no magic grease or oil to use. If it has the word "gun" in it, that's fine. (There are also plenty of other greases and oils that work well on firearms, but that is a whole 'nuther discussion.)

Simply, no.

Two contacting surfaces, are contacting. Lubricate them.

The main difference between grease and oil is their tendency to migrate at a given temperature.

I use a tub of white lithium from Auto Zone for all of my guns. ALL.

Lubrication is not a great mystery, Flork was overkill.

White lithium grease for the win. I bought a $5 tub of it years ago for just such a purpose as Arc’s: all lubrication of my firearms. It will outlive me. For the things in life that specifically require oil, RemOil will do until I can find a cheaper replacement. I’ve used 3-in-1oil as well. Need be no more complicated than that.

I agree with Rogue here.

Both have their strong points and weak points. I wipe down metal surfaces with a quality gun oil, ( based on decades of personal and industry experience, I can't include rem-oil, or the flash in the pan/wonder lubes from frogs and crisco ) for basic rust protection and grease for moving/metal to metal surfaces.

Lubriplate , a tub will last a lifetime

I use oil on every gun and the owners manual of most all of my guns say to use oil. I have no abnormal wear or any lubrication issues on any of my guns and many of them have a good amount of rounds through them.

That being said, on a SIG with an anodized frame, SIG recommends grease and they need grease due to the dissimilar metals. That would be my exception and I'd use grease on the frame rails etc.

I use grease (Slip2000 EWG) for all of my pistol rails. Even for my Beretta 87 Target, although most folks use oil for .22LR pistols. Cycles perfectly, even though my ammo is Aquila Pistol Match, which is at the low end of standard velocity.
