Look at the posts in this thread. Many people are conflating the two platforms. I think the the Browning lock up matters just the way it does in a 1911. Again it does not mean there is not another way to skin that cat. Lets look at what effects accuracy on a 1911 and then apply it to the P210. 1. Minimize frame / slide clearance -- 15% 2. Install match grade barrel -- 10% 3. Fit / install accuracy bushing -- 20% 4. Minimum chamber headspace -- 10% 5. Eliminate rear barrel side play -- 20% 6. Consistent full barrel lug engagement -- 20% 7. Beyond reach -- 5% To me 40% of the of what makes a 1911 accurate has to do with barrel lock up and engagement. Again not that you can't do it another way but with skilled craftsman like the Swiss this is why the old P210 is what it is. It is possible that Sig is getting equal performance out of the new P210 but I have not see a factory test target at 50 meters from a US produced P210 like the one I posted. I have not seen any verifiable testing over 25 meters. The Swiss guns ability to do that was not just the stuff of legends. As to the Sphinx IMHO is a great comparison. The current US made Sphinx SDPs are not as good as the Swiss made ones from just a few years ago. The new SDPs are not as good as the old Sphinx guns. They changed them not to make them better. They changed them to make the cheaper to produce for the mass market. A true Sphinx from Switerland will cost you $4800+. I believe the Sphinx analogy is spot on. The SDP made in the US is full of compromises to hit a price point. They are great guns I own 2 of them but they are not on the same level as the guns that came before them with the Sphinx name and are not the equal of the guns made in Switzerland today. https://edelweissarms.com/sphinx-3009-compact-duotone-1787/ I am not trying to piss on the OP. The current Sig P210 will be an awesome present to his brother. My comments are informational because everytime the P210 comes up it seems like 50% of the people commenting do not know the history behind the gun and are viewing them as equal which IMHO is exactly what Sig hopes you do. Anyway I am out on this one OP I hope your brother loves the P210 and it serves him and his family well.
