A bit more of a drive, but Mace Outdoors in Mebane (just off I-40/85) has a wide selection and the staff will let you handle any and all handguns you think might fit. They have a rep for being woman-friendly (no gunstore cowboys here). I've been doing business with Bill and Linda Mace since the early 90s. I have been tempted to put them on my tax form as a dependant.
If for any reason she is down in the Southern Pines area, Ed's Gun Shop is also a very nice place to shop and he also has a big selection of used guns. As you know Southern Pines is a destination area for retired wealthy folks and he buys whole lots from estate sales, cherry picks the really expensive pieces, and sells the rest at bargain prices. My mate has bought a number of items from Ed, most recently a 1930s production Colt 1903 in midnight blue with ivory grips. It came with a lot of Purdy shotguns that Ed resold to a collector out west and the Colt was just lying on the counter when we walked in.
I used to have a number of friends and family in Durham. They've all moved away. The town is run by crazos.
