So after 30 years+ faithful service, I was in a class Sunday and the Trigger Bar Spring busted - when I got home I looked at several sites but all of them said "out of stock" and no date of expected restock and you couldn't backorder it. What to do, checking out other SIG's on hand the spring for the P220 had the exact shape I wanted so I removed it and tried it in my P225 - Ereaka it worked - checked the parts for P220 availability and have two springs headed my way.
Hope this helps someone out.
