Good advice about having her chose her gun and I agree. i am however in the same boat as the op. I am much more into guns than my wife so it is falling on me to at least narrow the field. Going to shoot the firearm first is great if you can find a range that has the gun you are looking for as a rental. Some of the possibilities are "off roster" so that makes it more difficult. I know you guys can't pick a gun for my wife, but you may be able to steer us in the right direction. My biggest hurdle for my wife is she loves the glock trigger an hates long DA trigger pulls. She wants a .380 is single stack configuration because she is petite and does not want to carry anything as thick as my G27.
Thanks for any input and it hopefully may be of help the op as well.
