Oldies,
Very, very nice! Looks like a factory gun which I very much prefer to a conversion with all kinds of bells and whistles stuck on it! The flat-topped frame is a great touch too!
Did you do the work or do you know who did the work?
Original barrel re-bored to 44 or a shortened 44 mag barrel?
Original 357 cylinder reamed to 44?
If I hadn't just done one, I'd grab it! But I'll pass the word in my circle of Ruger nuts.
