This holster is designed for smaller guns to be carried IWB. It has a J-hook for your belt that mounts low on the holster so you can tuck in your shirt between your pants and the holster.
As a service technician I wear jeans or shorts (depending on the workload for the day) with a company T-shirt every day. Normally untucked, but I do tuck on occasion. Working outdoors for the most part, wearing only a T-shirt, I can not conceal my primary carry weapon. (H&K USP .45 full size) I then carry my BUG only. A Kel-Tec P3AT .380 in the Galco USA holster.
It has worked wonderfully. It does not move or shift about. As small as it is, I had thought it would. Neither sweat from a hot day, nor the rain we have recently experience have created any problems. It holds tight working in any position. I am often stooping, crawling, on my back, etc... I feel it when I first put it on, as with any holster, but soon don't even think obout it. (unless I happen to roll over on it....ouch!) It is very comfortable.
The only problem I have had with it was finding the most comfortable position. (just in front of 9 o'clock) I carry it on my left (weak hand) as it is my BUG, and I primarily shoot it at the range with my weak hand.
