TGS is great to deal with. Items are always in stock, priced very competitively, and shipped lightning fast.
They are also willing to do their homework to assist a customer. I live in Cook County in Illinois, but not in Chicago. A lot of online sellers will not sell hi-cap mags to anyone in Cook County even though it is perfectly legal to do so, since they are only illegal in Chicago. I ordered three Glock 17 round magazines. TGS verified my address and I had the magazines in a couple of days.
