Back to OP -
William,. you posted "for your daughter" and I'll assume it's the same daughter you posted awhile back about concerning gun ownership,etc. Has she gone through one of the training courses, or have you trained her up accordingly? Not an argument, just a question. I just gave my 24year old daughter my Ruger MKI 22 Auto last summer. She picked it out after a day at the range as the one she would like "when the time comes", so when we left to come home, I left it with her. I am noise sensitive, having lost my hearing to loud music, a 357mag, and improper hearing protection. I've read on here that the 327Fed is a terrific little round and as loud as a 30carbine in a revolver. This I would not get for my daughter. I would probably lean towards one of the new 44Spl's with a short barrel to help compactness. I'm understanding this not to be for a hunting or target purpose, but for self-assurance. The down-side of this is your daughter probably will not be handloading for this and expect the lighter revolver will probably have some recoil to contend with. The up-side would be if she ever "had to use it" in a hurry, she'd still be able to hear.
I have a friend in Wyoming who, at the request of some friends, taught a lady's group how to use a handgun for fun and defense. Given choices after they had been on the range, they all chose his 44Spl or his 45Colt revolver over his multitude of handguns in 32-20 up to 45acp. They cited control-ability and lower noise levels of his 4" 44Spl and 45Colt, prefering the larger revolvers.
I prefer Rugers to S&W from a price perspective. I bought several S&W's before we started having kids, and between diapers and child-support, the S&W's got sold and replaced with Rugers. As stated, I gave my daughter my Ruger 22 - totally because it was her choice and it was totally not for defense. If I were getting her something for fun and defense, I would look strongly at a 44Spl AND a S&W for all of your reasons; fit, finish, quality that only money can buy. I would not get her a single action in anything for defense. After all, she is my daughter and started shooting shortly after she was out of diapers.
I think you have your mind made up - and that's fine with me - it's all about choices and decisions. Whatever your choice, it will be a good one, and you will have put a lot of thought into it. After all, she is your daughter! Best of luck with both her and your decision!
