Welcome! I'm from Austin and just recently received my permit in the mail. Yeah, I know what you mean about the Texas summer heat. I decided to carry a Walther Pk380 in a holster that I place in the small of my back. Talk to others and try going to a gun range where they will let you shoot various guns before you decide on a different gun. There are many small pistols out there that are good to carry even in the brutal heat. Some of them you may even forget you're carrying! You've made the right decision to carry because the thugs in this world are not in business to shake your hand and give you a kiss! Remember to always carry and never hesitate to draw your weapon if you have to protect your family.
