Hey Broker....thanks! I appreciate the find. However, my P220 is a newer one so it has the 10mm trigger. I'll hold off and see if I can find a newer, 10mm width trigger that is NOT the skinny version.
Just called Sig....going to be at least a month on those, as they're all out of stock. Same with the 8 round magazines for the Sig P220. My goodness....I didn't think it would be this hard to find a simple part for a very common gun. Makes me want to go back to Glocks, as at least there are a thousand different vendors for Glock parts...
But in seriousness, I'm going to post a for-trade ad in case someone wants to go from regular-to-skinny on their trigger. Apparently the standard trigger part # is 34260200, and it's the same trigger on the P226, P228, P229, and P220, so that's at least somewhat common. Thanks for your help, and PM or e-mail me if you come across one!
