Sig p220. Is this normal wear?

SIG slides often wear quickly. My West German P226 slide lost its finish and began surface rusting after less than 18 months in my duty holster. I had it refinished in Np3 from Robar back in the early 1990’s and the SIG slide finish issue on that gun was finished.

As was posted above, that is from a rail rubbing on the slide. It happens to many semi autos, your P220 (Which IMHO is a great .45!) will be fine.

Stay safe.

I know lubrication can be a loud and opinionated topic, but I am going to recommend using a semi fluid grease on the slide rails and where the barrel touches the slide. And underneath the slide too.

Since semi fluid greases are not sold at Walmart or Automotive store, Americans are unfamiliar with them. Most have been exposed to semi fluid greases during a military tour, when they used LSA. LSA: Lubricant, semi fluid, automatic. Military LSA is great stuff, but can be hard to find, and expensive. It is also old lubricant technology. Has a tendency to separate, you have to shake the bottle before squeezing it out.

I have tested several commercial semi fluid greases, and this one has been the most successful: Farm Oyl Fluid Grease.



It is thicker than LSA, about a warm honey thickness. It does not have a "gear oil" smell. Most of the semi fluids I tried are made for gear boxes and smell like gear box oil, which I find objectionable. Since this stuff is black, I think it may have molybdenum disulfide suspended in the grease. For me, this semi fluid is not drying out, such as I have experienced with oils and LSA. LSA will flow out of the rails, and that gets messy in storage. This does not. Its surface adhesion has been excellent during shooting sessions. I tried other LSA's, this is the best to date.

Why not use what Sig says to use? I think Lucas gun grease fits the bill

If you try to buy LSA (especially at an auto parts store) make sure they arent selling you Limited Slip Additive for differential gear lube.

Possibly, but probably not

I use TWB 25 on my 226. It does a great job preventing wear. There is always a decent build up in the area you are concerned about.

The guys at the auto store did not know what a semi fluid grease was.

This is the good stuff






My older LSA came in green cans and green plastic bottles, the color of the container is unimportant compared to what is on the label.

Just in case you have been wondering what lube to use on your MK19 automatic grenade launcher.

I guess Lucas not the flavor of the month any more.

What about good ‘ol Lubriplate? I use it on everything where grease is required

Any light grease will work, it’s not rocket science.

My oldish commercial German-proofed (geprüft) Sig P225 seems to have very little accumulated external wear with regular

lightly-‘geschmiert’ Mobile One reddish grease on its rails, plus very thin Ballistol underneath.

What grease, if any, is issued to, or chosen by our Spec Ops and Special Forces (Delta etc) teams?
