Undershirt, for the young guy's it's a "Wifebeater"
When it's super hot like this weekend and I can only handle a single T-shirt, I pocket carry the LCP. Might be a little under armed according to some, but it's comfortable and therefore ALWAYS with me.
been thinking about an LCP for summertime carry, the FNX in the super tuck is hard to not print with normal t shirts, button ups and loose polos are fine but wear a fitted t-shirt and its a no go
I do the same thing. A tank top style t xhirt under the normal shirt keeps the gun off of my skin. Also, I have switched to carrying a Glock this summer where as last summer was a CZ 75 Compact. The CZ would rust up if it got sweaty where as the Glock does not seem to mind.
I carry a Kimber tactical-pro II with a clipdraw in the small of my back . No problems carrying or covering with just a untucked shirt .
