I apologize if this is OT. It's not really an OC question but I'm hoping someone can help.

I'll be visiting my mother in Pittsburgh over the holiday weekends coming up. She's interested in looking at firearms and possibly purchasing. I don't live in Pittsburgh and am not home often enough to know where reputable gun stores are located. I'd like to go someplace that has a good rep, rather than just Google. Is anyone familiar with Murrysville? Can you recommend a shop where we can do some window shopping?
