There is the Starry range
If you plan on being in Corpus for any amount of time you can get a membership at the Corpus Christi Pistol and Rifle Club
If you are looking for a polymer handgun, the Smith & Wesson M&P is 2 steps above the Glock. The XDM took most the M&P's improvements over the Glock and added a grip safety, but the XDM's ergonomics are still not as good as the M&P.
If you are looking for something small in .380, the Walther PPK is top of the line.
I was down on Sig for a long time (the ones that I was issued in the squadron were worn out) but I have a new P-226 Navy that I am in love with.
Screw ranges. I just stay at home and shoot my TV.
