A little over 3 years ago, my wife and I were fortunate to have our first grandchild.....and it too was a boy.
By the time his first Christmas rolled around (about 3 months), I had picked him up a Springfield XD9. I didn't feel it wise to start him on an XD45.
When I told his mother about it, she delivers me a "Dad, he isn't even 3 months old yet."
I told here to relax......he wasn't getting any ammo until his first birthday.
