I'm a member at Lozano's Shooting Range in San Manuel. Really nice looking place with down to earth people, it really felt like a club and not just a range.
I was really disappointed when Lozano's range west of San Manuel closed. The Mission Skeet & Trap Club has an outdoor pistol range, I believe, although I've only been over there for an archery shoot my daughter was in. Shooter's Alley in Mission has an indoor range. I frequent Pointblank Sporting Goods in Pharr myself, for both the indoor range and, of course, for the indoor archery range for my daughter (who prefers her shooting in air conditioning, if she can get it).
