I was looking at a S&W revolver for the wife to carry but probably in 22mag as she really does not like recoil.
My first pistol was the basic S&W Sigma in .40cal and I'm pretty good with it. It has a very heavy trigger and if you learn on it all the other triggers are easy and it made me a very good shot learning trigger control.
It was my concealed carry for a while but I found a smaller KelTec PF-9 is an easier pocket carry as I usually have my shirt tucked in and summer is here so plaid shirts are out for the season.
