I agree with those that say let her pick her own. Mine (not wife but close enough!) carries a S&W 360 M&P. We went through several auto's but couldn't find one she could manipulate EVERY time and suffered several broken nails and a lot of frustration. She eventually spent a couple hours at a gun show and handled many handguns before deciding the 360 "fit". She carries .38 Spl +P's and practices with standard pressure 130 grain WWB. Although the 360 is a .357 Mag it is very uncomfortable to shoot with the magnum rounds.....almost akin to slamming your hand in a door.
