I handled my first P-210 three years ago at Simpson's LTD. In Galesburg, Illinois. I had always criticized the "Myth" of how wonderful The P-210 was and how it was the standard by which all other auto pistols were judged. I particularly disliked the mag release. It looked to me like a flimsy piece of crap that belonged on a cheap Spanish knock-off.
I examined a military model alongside a commercial model. As the Aussies would say; I was Gob-smacked. The first thing I noticed was that there was no difference in quality or fit and finish between the two. Frame to slide fit was flawless....no side to side play and no up and down. And this was checked with the gun field stripped and without the barrel in place. That is the true test of a proper frame to slide fit.
The machining and polishing were peerless. The gun just had that "feel" about it. In operation it was as slick and smooth as motor oil on a glass doorknob. Then I tried the trigger and my knees got wobbly..I have never felt a trigger like that. Almost like a three stage, with the second stage being easily felt, right before a crisp, clean let-off. I was shown the factory target that came with the commercial gun. From a rest, a 2.5cm group at 50M. 1" at 54 yards!
The legend is true, as far as I am concerned. I would put my avatar up against a P-210, BUT: We only made a handful if those things per year. Sig turned out thousands of 210s every year. And they were all flawless! The 210s were an actual mass produced pistol. To hold that level of quality during mass production is an incredible feat.
Of maybe it's just Swiss......
