Well, start here;http://www.gunsandammo.com/
Also there are blogs all over about different disciplines.
You could go out to the Addicks Range since your around Houston I think. It is Bayou Rifle & Pistol Club. They will have scheduled matches and instructional days at the range. Not knowing how much you know about shooting and guns I would highly suggest talking to the clubs that are local to you. Most all shooters and range officers will help you face to face and that could help with safety and point you in the right direction for what you may enjoy.https://bayourifles.org/
is their website.
I used to know most of the folks that ran it but I haven't shot there in competition since 2005. There is a guy, Bruce Mahon used to be on the range board there and if he still is he would be happy to meet and teach you. There is contact information on the website and I know they used to be out there every weekend with range officers, instructors etc.
I again must say anyone new to the sport will greatly benefit from a face to face introduction to shooting and firearms. After your initial contact you may see that you would more like to concentrate on one style or another. Try just reading about some different disciplines and ask any questions you may have.
Meanwhile.........Off to the bay for a day of fishing for me.
