I your wife wants something simple to start with I use a couple
FOBUS holsters off duty. Polymer type made in Israel. They are inexpensive; absolutely foolproof; indestructable. I have carried one on horseback in the backcountry for a couple years. The weapons stays in with a snap. There are mag holders as well. I use them on my belt under clothing or anywhere I can hook them. Just look up FOBUS on the internet. Or, you can get them at some gun shows. At our state Academy that is all the instructors are using. Good and reliable.
What doesn't kill you makes you stronger.
