Slight discoloration on slide, half moon shape. Only slightly noticeable when holding gun at an angle. I've noticed the same shape/discoloration/location on a few P232s, anyone know the cause of it?   This message has been edited. Last edited by: rbschneider1, | ||

I recall one of my past P230/P232 pistols had similar marks. I believed it was caused by racking the slide over the years of ownership. Did you try wiping it down with oil? A very light rub down with a mild grit 3M Scotch pad might reduce the mark if it's of concern. Beware of a man whose only pistol is a 1911, he's probably very good with it. | |||

Yes, tried oiling the area, no success. Not sure if it is from racking the slide, the others that had it, were identical in size, shape, and location, seems like something else is causing it.This message has been edited. Last edited by: rbschneider1, | |||

yep...pretty common. Not sure the reason. | |||

I had a black 232 that I sent off to Robar for NP3 coating. Came back with the same half moon you fellows show. Never saw any flaw in the slide when it was black. How did this happen ? | |||

Since it is occurring on numerous pistols in the same spot I suspect the discoloration is being caused by the tempering process. | |||

I suggest a non-abrasive chrome polish. Can’t hurt, might help. Serious about crackers | |||

UPDATE....... I decided to contact the creator (SIG) about this, here is their explanation: "Thanks Ronald, it is what is suspected. What you are seeing is the “shadow” of the slot on the inside of the slide for the disconnector. Its curved so the disconnector slides down when the slide cycles. Because this area of the slide is thinner, you can get that shadowing and its likely a byproduct of the heat treatment. It will generally be more pronounced when the slide has been refinished (bead blasted) because that makes the finish a bit thinner and will be slight or even non-existent on slides that are nitron finished. It is normal and to be expected and is not indicative of any defect."  | |||

Cool. Thanks for the follow up. --------------------------- My hovercraft is full of eels. | |||

Here's the one I had Robar do some years ago.  I can't see this shadow on any black 230 or 232. | |||

I had to go dig my stainless 232 out and have a look. I don't have the shadow. | |||

My SL slides don't have a "shadow" either, just seems to happen to refinished slides. | |||

Happens to both refinished/not refinished... Per SIG - "It will generally be more pronounced when the slide has been refinished (bead blasted) because that makes the finish a bit thinner"This message has been edited. Last edited by: rbschneider1, | |||

I have noticed similar marks on nickel P228s but not on stainless 230/232. Probably same reason though- heat treat- as the marks are in the same place on multiple guns. | |||

I agree. I would like to see a pic of a black(unfinished) 230 or 232 with the half moon shadow. None of mine have any trace. | |||

I have never seen a "blued" P230/P232 with this shadowing, only seen it on stainless steel. | |||

As noted by the experts at Sig, you won't see it on a blued or coated gun because the coating covers it up..... and it shows up more on the bare stainless one that have been polished by some means. My Native American Name: "Runs with Scissors" | |||
