I have been to The Gun Store a few times and I have to say service could be better.
Out of the handful of times I have visited, including once to take their Conceal Carry course, I have only met one employee who was kind. The rest ignored me or were downright rude. As far as the range goes, it is a nice one, but is way overpriced compared to some of the other ranges around town. Same goes for their selection in store.
It is almost always packed in there and if you plan to shoot, you need to go early and avoid the weekends.
