I recently had a chance to spend some time with a pair of P210s.
One was a heavy frame model from the very end of original P210 production where they were mostly built in Switzerland and finished up in Germany. The other was a new-production Sig-Sauer target model that was purchased in the hopes of sparing the original some miles and wear and perhaps be suitable for some competition sports.
It was also hoped the ergonomics would be better with the push-button mag release and such.
OK, so what I don't like about the original P210:
The 8-round mag capacity is a bummer, no way around that. What makes it worse is the magazine spring is very stiff so it's unusually hard to load.
To make matters much worse the heel-release is extremely stiff to actuate, so much so that a person without my hand strength gave up on the weapon after just a couple magazines. I don't usually mind a heel release particularly but this is the worst I've ever used.
What I like about the old 210:
Well, of course the trigger is amazing.
The weapon is also accurate, yeah, shocking I know. :-)
I had to move back to 50 yards to really get a better sense of how my loads were printing at which point the average was about a 5" 10-shot group off the bench for me.
It was interesting to see how much things opened up between 25 and 50 yards, in particular the plated bullets just did NOT hold up. The Hornady XTPs out-performed the Sierra V-crown by a significant margin.
That said, under 25 yards this thing was more remarkable for how consistently it shot good groups with almost anything. It was far less fussy about bullet profile, powder, whatever, all shot well and with a lot less POI shift with different loads than I'm accustomed to. Whatever that magic is, I really like it. I'm also a little surprised that that isn't more remarked-upon in other folks notes about this item.
Reliable, yes, perfectly despite a wide variety of profiles, lengths, and power levels. The only thing was the first round from the first mag sometimes needed a little push to strip and chamber the first round.
OK, so how did new production stack up?
The trigger was still excellent, anything I thought it was lacking was subtle and likely just made up in my head because one was "old world craftsmanship" and cost 3X what the other cost.
The look did change, they moved the safety and slide release to improve ergonomics and make the drag-mark the originals made under the safety go away. They also changed the lockup on the weapon. The new one has a wider slide, which makes for a wider frame and overall just a wider weapon. This makes an already full-sized sidearm even bigger. They went to a push-button magazine release sure, but for my average-sized hands I can't reach it! Remember this is a SINGLE STACK 9mm here and it feels bigger than a 1911. I can't get to the slide release with my right thumb either but the mag release just hurts. More magazine misfortune, it's still an 8-round mag. On the target gun they put some extra long grips on the gun so put an extension baseplate on the mag, it would have been so easy to make it 9-rounds or even a nice even 10 with a little follower work, then you could at least run limited-10.
Speaking of those extended grips, they increased the length of them making the weapon feel a bit clunky and also increased the magazine opening to accommodate the extended baseplate but it has a sharp edge so exactly fails to act as a flared magwell extension. The magazines are also somewhat difficult to slide home over the release. So rather than really fixing the worst part of the old P210, they just make it less bad.
Accuracy... well, it's fine but not amazing. A little worse at 25yds and a lot worse at 50 yards. I didn't run as many rounds through it as the old generation one so it's hard to quantify but looked about 30% worse.
Reliability is actually better. No failures just like the older P210 but feeds the first round very smoothly and easily as well.
The grips are comfortable and fit well though they are much longer than I'd need them to be.
The grips and the size of the weapon do make it amazingly soft-shooting. "About like my Trailside .22" said someone along for the experience.
The undercut below the trigger guard, beavertail, and hooked trigger guard all make it less like the original, weather this is a good thing or bad depends on what you like, so whatever.
Also, it's just a little thing, but the fiber-optic in the front sight is visibly off-center. Just the sort of thing you don't love in what is supposed to be a target firearm.
Overall I *really* wanted to like the new P210 "Target" model from Sig Sauer and for it to capture the magic of the original but at a more affordable price, but it wound up being a compromise that weakened the original's strengths and only sort of redressed it's shortcomings... that's a little bit sad and boring.

I have a SigP210 Target and its nice to shoot but after around 100 rounds the recoil spring guide snapped! Certainly not bullet proof like my 226s and 229 that I carried for 18 years with over 30k of GD .357 Sig. Disapointing to say the least

I passed on purchasing a new P210 after renting one at my local range.

I found the thumb safety edge to be waaaaay too sharp. If I owned it I would have the edge either beveled better , or filed "fatter". And why spend $1100 only to immediately have to modify?

Just my $.02 after 200 rounds.

Accuracy at 25 yards, two handed unrested, was in the 4" range.

Just didn't float my boat the way I thought it would.

YMMV.

Thanks for your post. I have to admit I’m a little bit curious about the new production guns. I can’t think of any handgun more “consistently overrated” than the SIG P210. (Maybe the Luger?) But I’ve never had the chance to shoot the new one, so I can’t comment on it. My Swiss buddies would probably “unfriend” me if they see this, but I can’t understand how they got that pistol so wrong when they had two very fine examples to follow (the 1911 and the P35).

That said, I’m in no hurry to get rid of my own P210.

I'd just strongly advise finding one you can borrow for a trip to the range before spending money on one.

"I’m in no hurry to get rid of my own P210."
Thusly truth is spoken.

I guess to each their own, but I think the Sig P210 is a way, way better pistol than the Browning Hi Power. I have several of both.

I've enjoyed owning and shooting 210s on and off since the '80s, but can certainly understand that 210s of any generation or type are not for everyone. I also enjoyed owning and carrying 1911s, Hi Powers, traditional SIG DA/SA guns, etc., but numerous other shooters don't see the attraction. We in the US of A are fortunate to have so many options when it comes to firearms.

I think it's fair to say I would have been more impressed with the American if I hadn't shot the Swiss.
I think the response to the review linked that resonated with me is it was shot at 25yds and it really is at the 50yd line where you separate the truly exceptional from the merely very good.
