I bought one a few months back, but haven't run enough rounds through it to have a hard opinion on it...that said I like what I have seen so far.
I like the platform the Sig offers of DA/SA (which I know many do not). With the steel frame and heavier slide, it appears to have the mass needed to handle the cartridge well without self destructing, and I plan to try/use heavier loads and bullets with it when hunting. Magazine capacity at 8 rounds vs 15 for my Glock 20 is not a major concern for my purposes.
Accuracy has been adequate for me...in the order of 2 inches or less consistently at 25yds with the limited loads I have tried. So far, no FTF or FTE.
Mine is the same setup as the Gunblast review shows, and so far, I am of the same mind as Jeff Quinn in his opinion of it at his website --
http://www.gunblast.com/SIG-P220-10mm.htmThere are other configurations available with adjustable sights, which I would like to add at some point, but I am not a fan of the SAO, which I understand the others are.
