There's a distinct possibility it would, but you won't know until you ask them!
On newer slides which are stainless steel, I wouldn't see a problem, but on grip frames, which are anodized aluminum, I could see a problem! But, once again I'm not Sig!

Yea - I could understand the engraving being a problem because it actually changed material - But I would hope I could cerakote from an authorized distributor...

Just talked to SIG - they said that painting and engraving will not affect warranty unless the warranty claim would involve the painted/engraved area specifically (for example: you crack your slide right on the engraving). That's preety much what I expected.
