Not sure where in Houston you are, but the Shiloh Shooting Range has a "Pistol Fundamentals" class frequently on Sunday evenings (starts at 6:15). They are located on Shiloh Church Road near FM 249 and 1960. It's not every Sunday, but tomorrow (8/2/15) they have one. Normally they have it on the 2nd and 3rd Sunday of each month. It costs $35 and lasts for about 2 hours. You can give them a call (281-444-8930) for more info.

They generally concentrate on one area each class, and in the past they've had shooting from compromised positions, magazine changes, shooting on the move, decision making, low light, and several other topics.

The have a few short videos on the facebook page (Shiloh Shooting) that show some of the events.
