Good for you, I wish I could get my wife to shoot with me. She will accompany me once or twice a year to the range simply out of guilt. She rarely even gets out of the truck, she is just along for the ride.
I have it even worse... When my wife goes to the range with me she tries to use as much ammo as I do... She doesn't limit herself to the small calibers either!! Oh, wait a minute... my situation is completely different
My wife "Qualifies" once a year... then isn't interested for another year. She did say that she wants to go shoot the new Ruger SP101 I got for her. I'm going to start her out on .32 Longs then 32 H&R Magnums then .327 Magnums and see what level doesn't hurt her hands. Arthritis is a pain. I hope she likes it enough to come out more.
