I second the above... Welcome! You're among friends!
Let me temper my Pietta bias comment as well... for a few dollars more than a Pietta, you can get a classier pistol that does not have garish "Made in Italy" and all other sorts of markings on the sides of the barrel. To me... that's a deal breaker. For others... well, maybe not. You pays yer dime and you gets yer ride and as long as you're happy, you are happy. Uberti's do seem to always be "just" a little nicer than Piettas, at "just" a few bucks more. No offense intended, and if they revised their barrel marking scheme I might actually consider them.
You'll love your Walker. They are a hoot to shoot.
