I don't like to resurrect dead/dying topics, but since I started this one, I thought I'd give an update (just so people know their input meant something)
After some looking around and handling guns, I got a S&W model 66 with a 4" barrel. It came with a Hogue Monogrip, which I don't think is the nicest looking grip in the world, but it probably kept the cost down a bit and it fits my hand well.
I shot it today for the first time and it functioned very well and seemed pretty accurate when I did my part. My double action groups weren't too pretty, but I have very little experience shooting revolvers, so I hope that will improve quickly.
I only shot 38 sp. handloads (which are mild even by 38 sp. standards) so far. I'll work my way up to more potent ammo in the future, but for a while, the limited recoil/noise should be beneficial for working on good habits and avoiding flinches.
Thanks again for responses to my inquiry. So far I'm very pleased with the purchase.
One follow-up question: Can anyone recommend a holster you like? I don't have immediate plans to carry the gun concealed, so I'm just thinking something that's comfortable to wear to the range or in the fields/woods/camp.
