Here's my pre-printed universal answer to your question:
Go to some local club shoots. Take about 100 rounds of low velocity lead revolver rounds, .38 Spl or .45 Colt and a box of 12 or 20 ga shotgun shells, Dove loads. The Shooters will let you try all kinds of guns, including different makes, shapes, grips and actions. Then you can make an educated guess as to what you want. I suggest you go to 3 matches before you decide. Several people will likely have guns they want to trade or sale. If you're a club member you'll likely get a better deal. Also take an old felt Cowboy Hat and a thick wide belt to hang a holster on. Yep, you can pickup leather gear too.
I'm betting that you can save yourself hundreds of dollars by not buying before you try.
There you go.
