Hi everyone. I appreciate all of the replies from months ago. I had printed this thread a couple of months ago, but I left the copy at work. Though I had read it a few times, all the model numbers were still kinda Greek to me. I stayed up late last night and reread it online while looking at the models on S&W's site. I went to bed knowing I wanted a 64/65 or 67. (are these revolvers or Pontiac GTOs?!?

)
I bought a new Model 67 this morning.
I'll get my mom to a range in a week or two and see how she likes it. Though she's not too accustomed to guns, she doesn't mind pawing over them - not scared one bit, and she's always been a hawk about "where you point that thing." I don't have to worry about her not pointing in a safe direction.
While she was looking at the 67, I told her the difference in it and an Airweight. I told her about the recoil. "Oh, I can handle that. I won't shoot it enough for that to matter." Good attitude mamma, but let's wait and see what your wrist thinks! I told her once a gun tries to jump out of her hands and scares her, she's going to have a hard time overcoming that first impression and the larger 67 is better to start with.
And... I had been wanting an Airweight anyway, so I went back to the LGS after lunch and got a 638! It'll be interesting how she reacts to it after starting with the 67. I would bet money she's going to agree the steel 67 is easier to shoot. Heck, I am curious how *I* am going to react!!! I've never once thought a .40 S&W's snap was that big a deal, so I hope the Airweight doesn't bother me.
Revolvers. What have I been missing??? These little puppies are too cool! I can't wait to shoot them.
Thank you all again for the answers in April.
