Another +1 on what cheapshooter said. Never sell or trade anything. But then I've always been careful not to buy anything I didn't really like. In the end it's worth suggesting again to get the Walther and keep the Glock (at least for a while ... until you both see it really doesn't ever get used). You can always sell or trade the Glock later, but once gone it's gone. In the end it's her gun and ultimately her choice but it is a marriage so you both should be in agreement.
