Do not purchase one for her. Take her shopping. Let her give you input and try on more than a few if you can find them on the shelf. Look around at the range. I have let men and woman try any number of our holsters to see if they like them. Just like shoes....you have to try them on first.
that is what I ended up doing Went to Bass Pro shop not an ad or any thing just a statement of facts. While there we did not take in the firearm initally my plan as I already knew that they did not have any in stock. We had some time to waste So I asked her to handle a few other firearms She really liked the ruger sr9c so after that I went out to the car to get the sr22 checked it in at the front and found her a holster that she liked and she will use. It was a good trip because now I am going to get her SR9c as I know she likes it and finding ammo for it will not be an issue what so ever.
Not starting a caliber "war" here...simply stating carrying a 22 is only a bit better then not carrying. Wouldn't you be concerned for your wife's safety if she only carries a 22 against a big guy advancing on her?
In a word NO it has taken me 4 years to get her from refusing to even touch a firearm to wow this is fun. Past before our son was born guns bad! Present plinking is fun for the whole family. So no I am not concerned about her only carrying a 22 she is good with hit shoots tight groups with it and stingers feed every time and have never had one ftf.
So yes I am not concerned
