I introduce friends to shooting every few months. I've previously done this several time at the Red's north location, and everything has gone great there.
At the south location, the setup and staff are no good, especially for bringing new folk into shooting sports.
The range itself is designed poorly in a few ways:
The lanes are very cramped.
It's poorly lit.
The pistol lanes are not segregated from the rifle lanes.
The area where you sign up to use the range is in the small transition room between the range and the store proper...this room is normally used to limit noise that comes into the store proper from the range...such a room must have at least one door closed at all times for just that purpose. So you can imagine how loud it can get in there.
The staff showed incompetence in a few ways:
There were only three lanes in use. Despite there being a lane available with unused lanes on each side of it, the range officer assigned us to a lane next to someone firing rifles. It was not pleasant trying to instruct and ease new shooters in to marksmanship when the lane next to you is making noise loud enough to be felt in your body.
They also charged us as though we had rented three lanes, instead of renting one. At the north location, I have never been charged for using multiple lanes when renting a single lane for two or more people to shoot at.
If you're close to the Red's south location, do yourself and everyone you're with a favor and go shoot at Lone Star Range instead of putting up with a place that doesn't deserve your business.
