Hey, if that's what it takes for your wife to consitently carry, more power to you (and her).
I've run 50 rounds through a TCP (non-pink version, so man-card is still in force), and I found it to be a nice little pistol that was a pretty good point-shooter. My wife is finally coming around on the concealed carry thing, realizing that the Kimber Pepper Blaster she has carried for a while is nice but not entirely adequate. She likes shooting my 642, and the recoil doesn't bother her. That's probably the way she'll go, but who knows.
Cheers to your wife! (oh, and nice P220...)
