I had an interesting project with a P229. I bought one last year as a winter time project. I have to admit that the pistol was in sad shape. Over a few months I replaced all springs and pins, and it got a new hammer. Later I noticed a ding in the crown of the barrel, facilitating a barrel replacement. The sights, long since day light only, got replaced with Dawsons.
That gun runs like a fat boy after an ice cream truck now. I so see the appeal of Sigs.
