You may want to consider multiple options.. As you probably wear jeans more than shorts, My solution may not apply,, but it's food for thought..
Here in the Conch Republic, the weather is similar to Tx,, HOT HOT HOT.. The difference,, we wear White work boots,, with shorts..
Daily wear is shorts and T's,, Dress up for dinner and you go for the Polo or Guayabera.
I use the following:
- SMALL,, NAA .22 mag, w/ 1 5/8 inch,, under 8oz,, fits any-ware including neck harness.
- MEDIUM,, Glock 23 or S&W 940,, in either a small leather butt pak or my version of thunderware
The problem with butt paks,, EVERYONE knows you are not carrying lipstick. The only advantage here is all the touristas from Saginaw Mi have them..
The commercial version of Thunderware is fantastic. Sits comfortably. has room for spare mag. The down side is you need a loose fitting belt line so you can, if needed, pull the front out to grab Mr Big and not look like Pee Wee Herman...
I took an old sliding belt holster for a 1911, stitched up a velcro belt of moderately heavy 2 inch strap. No room for spare mag, but when positioned properly you can ware it inside your bathing suit.
The third venue is to get one of the .380 or 9 mm mini-me's and stick it in your back pocket. I like the looks of the 9mm Rohrbaugh, but for piratical use the .380's by Ruger, NAA, & Kel-Tec are better deals..
