I visited both store today, knowing that I would not find an M&P Shield or a Walther PPS. GP was clean and well stocked, the staff was three young guys; knowledgable and friendly. I considered a Beretta Nano but the lack of a slide release was too quirky for me. I took a good look at the XD SC in 9mm for $475. It seemed a bit high to me even though I've been out of the country for several years and I wasn't up to date. Since everything else seemed pricey ($550 for an SKS (!) even if it was Russian. So I headed up Countyline to SS.
A small store, not as well stocked, but very friendly staff and the owner Jay was there which is always a nice thing. I ended up buying the XD for $60 less than GP.
