Your going to have trouble putting it down Mike, I bought one a few months ago just like yours, 4/58"...it's plenty accurate, I haven't tried anything except 250 grain Keith bullets yet, but am real happy with how they group. I had Simply Rugged make me a holster for it. I have carried it concealed back when the weather was a bit cooler, and will again when the temp drops. I had been waiting for almost 30 years for Ruger to make the holes in their .357 bigger...they finally got around to it. I also had some nice flat bottom cut grips made by Cary Chapman at CLC grips. The only other thing I might change someday is the hammer....I think I need a Super Blackhawk wide spur hammer on it.
Have fun with your birthday present, you have a nice wife there.
