You are correct both are -1.The 3 in has the magnaport full package.This is my grail revolver. Never thought I would ever see one in person much less own one. Nothing special about the 4 in except it's mine. Both are great shooters.Nice pair o' 629's! Look like they are both -3 or earlier, and the Snubby has had some "Work" done to it--Maybe by Magna-Port or a similar Shop--So tell us all about 'em!
