The question came up in another thread, “How do you carry in the summer in Florida?”
I have been living in Florida since 2011 and carrying since 2016. I have come up with my ways to carry in the summer heat.
The heat doesn’t bother me, so I wear slacks year-round. My daily carry (Glock 43X) is in an UnderTech UnderCover undershirt - gun under my right arm, spare mag under my left. I have room for another mag under my right arm. I usually wear “fishing” shirts, tucked or untucked. They are blousy enough that my wife can’t see I’m carrying, and she knows where to look. I also have a few “Hawaiian” shirts (they’re dressier) that conceal even better because they are mostly large patterns, as opposed to the solid colors in the fishing shirts. I also ankle carry a Glock 43 when neither a fishing shirt or a Hawaiian shirt is appropriate. I wear 5.11 slacks. They might make me look like I’m carrying, but they’re more comfortable in the heat because they’re baggy. If I lose the weight I’ve sworn to lose over the past five years, I can go back to IWB with the 5.11s.
