I'm almost in total agreement with you......... If the OP wants new, and the budget allows, check out a S&W 686. If he doesn't mind used (which 90% of my guns were when I bought them) he will find a TON of S&W 686's for sale. I have 5 of them!
Anyway, great first gun, get a few boxes of wadcutters, I have never had anyone complain about recoil with them. Semi wadcutters for a little more kick. .38 Special for a little bit more bang, and then .357 Magnum for something FUN!
Shoot it in D/A to learn how to control the squeeze of the long trigger pull. Cock the hammer for S/A mode for the feel of the typical semi auto.
I shot a Glock once, have no desire to do so again. To this day I have yet to buy a "plastic" gun, but have shot some that I did like, the Glock I shot was not one of them though. TO each their own.
