Hi all.

Just picked up my 365 and broke it down for it’s initial cleaning. I noticed what looks like corrosion in the inside of the slide on the muzzle end. The metal is smooth, and it has not been fired or left out anywhere. Picture is attached. Any ideas? Is this normal?

Thanks

The slide of the P365 is made of stainless steel, not carbon steel. That doesn't really look like rust to me at least. Yes, stainless means stain less and not stain or rust free ,but I doubt your new gun has rust of any sort direct from the factory.

Shoot and enjoy you new Sig.

That is the result of the process of treating it to the Nitron finish. Usually where a fixture holds the slide. All Nitron slides will have that in places. I can't recall ever seeing a Nitron slide that didn't have an area like that and/or had it in tight areas like the slide's grooves that ride the frame.
