In a Christmas greeting, just sent out by S & W on Facebook, they featured a right side view of the new Model 19-1 Performance Center .357. Readily apparent was the relocation of “PERFORMANCE CENTER” from the left side of the barrel to the right, plus what appears to be a pin driven in below the barrel and just forward of the pin on the front sight. I can’t find a view of the left side to see what has changed there? Could the pin be retaining a second lock for the end of the ejector, or what?
