Nicely done by the Mrs. I know the feeling. My wife is now shooting with me, and it's a ball. Nothing like waking up in the morning, having coffee, and having her bring her weapons downstairs (.380, Remington .270, and an old J.R. Higgins .22) and tell me she's ready to go play on the range.
One thing I'll offer up? I bought her a 'limb saver' at Wally world. Paid $20.00 for it, but she swears it reduces the kick and makes it easier for her to handle.
Again, congrats. Now you can have romantic evenings at the dining room table drinking coffee and cleaning his and her firearms!!!
