MarketingGuy,
Get the .357 revolver. I prefer adjustable sights, but a fixed sight gun is simpler and "more rugged" in that you don't have a fragile rear sight. Shoot .38s. Keep your brass and learn to reload in a year or two. IMO, the most forgiving cartridges to learn to reload for are the .38 Special, .44 Special and .45 ACP. Just MO though.
I learned handgunning on DA .357s and a SA Ruger .357. And a bunch of different .22s. I believe this made me a better shooter than learning with a tuned 1911 or a a high-cap 9mm. Don't get me wrong; I love a good 1911 and won't part with my Glocks until I have no choice. But I believe the DA revolver is the king for teaching shooting skills in trigger control and sight alignment. Plus you won't have to worry about malfunctions.
And add a .22LR of some sort. $15/550 round ammo is good for learning how to shoot well. Granted, lately I've been burning up CCI Standard Velocity at $25/500, but I think the increased accuracy and reliability are worth it in my guns. YMMV.
Oh, shameless picture plug! Three good reasons to get a revolver:
Clockwise from left: M-18 .22LR, M-629 .44 Magnum, M-19 .357 Magnum.
Good luck, keep learning and stick around.
