CONGRATS
On a good deal for a really sweet gun, if that's the one you like best. I'm kind of on the other side. In 1983, I got a 7.5" .45 Blackhawk convertable, and since then, haved added another one, a .357, a .44 Mag, and three original Vaqueros in .45 Colt. I also have a new Vaquero in .45 Colt, one of the ones with the faux case colors. NIB 12 rnds fired, so far. But I have handled it a bit.
I'm not crazy about it. Its a great gun, just not what I'm so used to. It feels "small" to me, and I don't care for the grips. Entirely personal preference, I like the oversize Pachmayr rubber grips for my Blackhawks, and I like the adjustable sights on magnum revolvers. So a .357 New Vaquero isn't my cup of tea, exactly. I do love the Ruger SAs though, and wouldn't pass on a good New Vaquero at a good price. They do feel like a Colt in the hand, but with Ruger's safer mechanism.
Because I began my SA experience with a new model Blackhawk, and used them for so many years before learing a Colt size gun, the Colt size has never felt "right" to me. Most folks are just the opposite, loving the SAA and feeling the bigger Rugers are "huge".
I do a lot of my plinking one handed, the old classic target style, and can ring the rifle gong at 200yds with my old 7.5" .45 Blackhawk, I have shot it that much and know it that well.
You got a fine gun, and once you have shot it enough with different ammo to learn where it hits with what (something necessary with all fixed sight guns), you'll have to look long and hard to find something better. Enjoy!
