I suspect that it’s the P226. The current US-made P210 is considerably different from its Swiss and German predecessors.

The P220 has been around longer than the P226, although the changes in both are essentially the same.

I’m thinking the P229.

The rest went from folded to milled after the P229, if I’m not mistaken.

What is your definition of "negligible changes"?

The P220 went from folded to milled slides, and a couple other changes.

The P229 went through the whole frame consolidation thing as there used to be separate frames for 9mm and 40SW.

And there are the rail less/tail less vs beaver tails and light rails.
trigger undercuts?

Internal vs external extractors?

Personally, I vote the P220 as it is also my favorite SIG platform. But it does depend on your definition of "negligible"

I dropped in an SRT kit into my late 70's Swiss made dolphin nose 220 in 9mm and it worked perfectly.

I consider all of those to be non-negligible changes.

I would consider changing the take-down lever from a two-piece steel part to a one-piece MIM part to be a negligible change. Also steel to MIM hammer.

A magazine from a P226 made in 1983 will work in a P226 made today.

A magazine from a P220 of the same era will not.

I'd give the nod to the P226.

What was the change that makes the old mag unusable in today’s P220?

The mag release mostly.

Thinking that would be a redesign that the P226 never had.

It seems the American mag release on the P220 was introduced around 1986 and the P226 was introduced for the US pistol trials of 1984. The real questions is negligible changes. I personally do not consider moving the mag release or moving from folded stamped steel to milled to be disqualifying changes. IMO, the P220 is the surviving granddaddy of the classic Sig pistols.

See, this kind of question really has no right answer, because, to paraphrase Senator Meachum, “Negligible is what I say it is”. Big Grin Everyone has their own concept of the term.

Overlooking the fact it was born a 9mm but now identifies as a .45 auto, the P220 is the true patriarch of the P-Series family. Smile

The first 220s weren't .30 Lugers?

It doesn't matter which caliber came first because the P220 was designed from the outset with multiple calibers in mind (the frame design is proof positive of this). Smile

My answer to OP is the P226 (because of my own subjective definition of negligible). Big Grin

Some of the early P220s were .30 Lugers, but some of the early P226s were .30 Lugers as well.

Honestly, I'm going to take a guess and say their 1911 is the longest unchanged. Once they got to Gen 2 after the GSR disaster they pretty much stayed the same and that's at least 20 years.
