Thanks for all the replies, everyone!
Well, it's now time for a range report. My wife and I went to the range today; a bit chilly (to us at least) and with around a 15-20 mph N wind blowing, but had a great time! I found that this 60-15 handles some rather warm 357 Mags with no problems and the recoil was actually tolerable for me.
My wife absolutely fell in love with her new pistol. I started her off with a box of 148 grain wadcutters and got her used to shooting the pistol and handling the recoil. After she finished those off, I had her shoot a box of some reloads with some 110 grain Sierra Blitz that should be right under Cor Bon's loading of that bullet in 38 Special. After she burned through that box, I gave her a box loaded with some X-Treme 158 grain RNFP plated bullets loaded to +P specs. And she didn't blink an eye handling those either and burned that box up too.
I ran around 40-50 rounds of some fairly hot 158 grain Zero bullet 357 Mag reloads loaded with 296 powder and you definitely could hear those going off.

And I shot a box of some 38 Special 158 grain X-Treme plated SWC bullets loaded to +P and it was nice to shoot with and pretty darn accurate to boot, shooting on the 7 yard targets.
I really like wood stocks on my pistols, but I have to say that I was actually very impressed with the rubber stocks that came with this pistol. They were comfortable to shoot with and seemed to take some of the bite out of the recoil. All in all, both my wife and myself are really impressed with the new J frame and both of us are looking forward to the next range trip. My wife was gushing about her new pistol all the way home from the range; about 35 miles.
