Are the current 2022's essentially identical to the first ones produced or has SIG tweaked the design over the years?

I just bought on for $469 on some sale at Range USA.

It's gut the stainless chamber loaded indicator, 1913 rail, and I think came with the small grip backstrap. Never looked inside one before now but the mechanicals look different than Classic P-Series and seem to be manufactured more like P320 parts.

sjtill has good info on the SP2022

The current production is not your Oma's Sigpro. Think fit and finish. Haven't handled a current production but it has been noted the Exeter Sigs no longer exhibit that classic hammer bounce.

Fit & finish as in better or worse?

^ in my opinion, compared to the German Framed versions, worse. However, they have probably improved compared to the first ones Exeter produced. Look for a diamond plate slide .
