I have to say, I dont know how people can carry those big guns. I'm in shorts and a T shirt almost all of the time, and I want something that I can carry ALL OF THE TIME. I have found my Kahr P380 in a horsehide Minituck is just about perfect. Extra mag in a pocket. When its cooler I carry either a Kahr PM9 or my Sig P938 in an Alien Gear Cloak Tuck. Its made for the Sig, but the Kahr fits in it like it was made for it.
I tried a Shield, but it felt bulkier than the other 9's. For me, when I carry, my #1 goal is not to print.
