I think you both would be happy with the ruger gp 100 ,3'' barrel. Iwould get it in stainless ,women as well as men like it in stainless and their easier to care for.
Yup, I got the same fever as you have. Right now I'm buying to hold awhile (shoot, of course) and resell in the future. I have several on Auction Arms as we speak...Take a look
I'd recommend the SP 3" as a first choice. The model 10 is something I hope to buy finally this year and I highly recommend it as well - 3" and 4" barrels are a better choice for accuracy. I dearly hope she doesn't make the same mistake I did when I got my first revolver - a 15 oz 442. I learned the hard way - "weight is your friend"....
P.S. Sweet guns Xavier - wish I had a couple in my collection - but I'm working on it....
