Trading only benefits the Gun Shop Owner...I prefer to sell things privatly & then buy new. Get as much for the old rifle as possible, then take Cash to buy the new toy for the wifey.
There are hundreds of nice pistols of many types available. The Beretta Neo might be right up her alley because it has different color grips (pink/etc) available. Gun Kote has paint available in almost every color so no matter what she decides, you can make it personally hers.
My wifey to be was looking at .22's all day at a gun show, almost got the Neo, then decided on a 9mm Taurus 24/7 Compact...go figure. You never know WHICH way a gal will go when you take her gun shopping
She had to get used to the kick, but she loves it
