Hi, OK, Texas Glockers is just a number, there are no meetups or shoots. Just kinda a fun thing.
GSSF is the best way to get an intro into competitive shooting. Easy stages, no reloads, no movement, just gotta have a Glock. And, since they do random drawings, you can win a pistol or cash. All you need to know to shoot is at http://www.gssfonline.com/ There is a match coming up in Dallas 3,4 May and San Antonio in December. A couple in Louisiana this month and in April.
As a newwbie, best advice is to arrive early, register if not preregistered, then sign in at all three stages, signing in at the one you want to shoot first last then stay there to shoot, since they squad from arrival time.
Shooting advice, do no hurry, take your time and make your shots count, a target miss is way more than taking an extra second to get on target.
Send me an email addy for you if you need any more info or whatever.
