The quick easy test to determine if wear is through the anodize layer:

Anodize is an intentional aluminum oxide that is "grown" on the parent metal. Aluminum is an electrical conductor. Aluminum oxide (anodizing) is an insulator.

Use an ohm meter and place both leads on the worn area to be tested (but not touching each other). Or one lead can usually be placed on the sear retention roll pin as that's typically contacting the underlying aluminum as well. The other lead can then be touched to the suspect areas.

If you get an short or conducting indication, you are on bare metal. If an open, the anodize layer is intact.

a good tip, thanks

Thanks for the tip. I just checked with my multimeter.

and I will say, its harder to do than you might think. The outside gray finish will conduct a signal, but the goldish colored wear spots will not. So for now its not worn through, as best I can tell.

I may still send an e-mail to sig. see what they say. cant hurt.

I am not a gunsmith, but IMHO it appears to me, to be normal friction wear (break in). Use more grease on the rails, the grease won't hurt anything.

I don't see anything in the pics that would concern me. Keep it clean and lubed and enjoy the shoot.

 

[rod442]

Thanks guys. And trust me, there's been enough lube on this gun. lol.

Wear on aluminum (or the preferred term: "alloy") frames happens. It's a pet peeve of mine too to see such rail wear on the expensive new pistol you just purchased but I don't see how you avoid it unless you're not going to shoot it. It appears normal to me but most of my experience to date has been with bright finished Smith & Wessons, not Sigs.

 

[Sigarms228]

That is normal and seen on all my classic P series SIGs including my German made one. The much bigger concern is if you see the same happening to a substantial percentage of the frame rails on the side of the frame.

Are you having any issues with the finish on the slide or frame itself?

 

[animalhd1]

None of mine do that! Kidding it's normal.

 

[MoRivera]

My DA/SA looks just about the same.

 

[mlazzaro]

Have to agree, that seems normal to me. Just breaking in. The finish is not going to hold up in those areas. It probably won't get much worse than it is now.

Nope. just on the top of the rails. Inside they look fine still. frame and slide look ok too.

What worried me was the appearance of being worn through the gold color underneath. According to the ohm test with my multimeter that was suggested, its ok still.

Ill keep an eye on it.

This is normal. It's hard to tell from the photos but this might be brass that is rubbed on to the surface and not actually wear. I have this on both of my legions that are thoroughly lubed with Lucas grease. I have 2000 rounds through my 229 and there is minimal wear on the finish.
