A simple search...
And I now remember reading that before -- it just didn't stick with me. I guess old age is getting to me... (sigh) And I'm sad to say that memory isn't the only thing that doesn't work as well as it used to, any more.
The P-210-6 I owned was a wonderfully accurate gun, but I found the mags awkward (and very expensive!) I wanted to shoot with it competitively, but just didn't have the $100+ a mag they cost (and it took forever to get them from SIG.) I waited 6 months for ONE mag. Nobody but Pro-Mag made after-market mags when I had mine. I got a couple of the Pro-Mags and spent a lot of time making them usable. They looked cheap but eventually functioned alright. (I saw somewhere recently that another vendor now offers them...)
I would have liked more than 8 rounds. The sights, when I first got the gun, made me bleed -- very sharp edges if you tried anything like a hand-over slide release, but a small file fixed that, once I figured out where the cuts were coming from! (As I was keying this I realized everyone complains about the CZ-75's slide inside the rails being hard to grasp, but nobody ever whines about the P-210 which is much the same. Guess darned few folks have ever handled one.)
A friend had a P-210 with the matching .22 upper, and ended up selling it because the hammer bite was terrible for him. I never had
that problem, but doing a fast mag exchange was a challenge. (I don't remember, but I don't think the P210 mags drop free. It's been years now since I sold it, but I suspect not as darned few guns based on military designs had drop-free mags in the European market.)
