I've never seen that before. Someone definitely didn't know what they were doing. :(

Cant imagine that not being intentional. Maybe it was a Monday. 😱

What's funny, is that it sticks out as far as the raised cocking serrations. The Milled slides were slightly wider than the folded ones, where the pins barely cleared the inner portions of the cocking serrations of the slides. Makes me wonder if these were an initial feature, later changed to the solid splined pins, while this slide doesn't appear to have a larger hole on the left for the splines. from these expanded views.

And, they aren’t very straight. I would think a Sport model would be straight up and down. 🤔

That was my original thought, too, evolution of the FPPP. But then, the one below with milled slide, also from 1996, but earlier than the one in OP (U568875), based on the serial # (U562491), has the solid pin. It's a head scratcher.

Are you talking about the Cocking Serrations, or the Roll Pin seams?🤔

Of course we are talking about 25 year old weapons too. Should one be an unfired, in known original untouched condition, that one, would be the benchmark! A closer examination, would be optimum!

Watching you guys go back & forth like this is awesome. Love it every time I see it.
The knowledge thats so obviously in your heads and not parroted threads, watching you sort it out never getting testy, just plowing forward to resolution.
When I get to the last post in these type of threads Im always like dammit lol Wish it could go on more.
I follow all the links, look at all the serial # info you guys put forth. Read it all for myself and I dont even have or will ever have such a project in front of me. :ROFLMAO:
If your a gun guy tho the knowledge is captivating to me.
99.9% of people would never notice this in the 1st place, you guys are on it like a duck on a june bug.
Just wanted to say Thanks while it was on my mind.

I don't think it's unreasonable that Sig would use whatever pins they had on hand when they assembled the guns. It could vary from day to day and from assembler to assembler. Finding a NIB example wouldn't prove anything one way or the other. It's very possible that two otherwise identical production pistols could have different style pins.

Roll pin seams. I’ve seen a couple where it wasn’t exactly 12:00-6:00, but never one that far off from the factory. If the older two piece weren’t traditionally shorter, I would think it has been altered.

I'm a fly on a wall here but wanted to ask if:
1- The solid pin replaces the older pin (inner & outer)?
2- What does the single coil pin replace?

I don’t think the solid FPPP “replaced” the the double pins per se. It was just part of the newly designed stainless steel milled slide that replaced the stamped carbon steel slide.

I believe there is a spiral roll pin to replace the double roll pins and I believe there is also a spiral pin to replace the solid FPPP. I don’t know if the spiral pins are the same, or two different ones. As I remember it the spiral pin replacement for the roll pins was not an official SIG part but was offered by a member of that other SIG forum, at least in the beginning.

Actually, I think it is more correct to use the word substitute rather than replace.

The new spiral roll pin is too small in diameter to use on carbon steel slides. Gerry R used to send out free of charge spiral roll pins that were the correct size to replace the double roll pin setup of carbon steel slides.

I’ve seen both used. My M11A1 has a SS slide and has the inner and outer pin. I’ve seen P229s with these pins from the factory as well. My guess is Sig uses what they have on hand to get rid of surplus supply. Kinda how we got P228Rs years ago.
