Actually Cowboy, you're in luck. I just recently received mine and will be updating a few other members here on my "review" of sorts. Lately I have been trying it out with 2 very different guns.
For grins I tried it with my Walther P99, fullsize poly frame. The shirt supports the firearm well and keeps it close to the body. The very bottom of the handle does tend to protrude slightly at the side of the Pec muscles. But then again, the shirt wasn't designed to carry a fullsize.
The next test was with a Ruger LCR. The LCR is very much in the same areana as a Taurus Slim, LCP, Kahr, PPS, etc.... The smaller framed gun has a tendancy to drop a little lower into the pocket of the shirt, but is still very accessable. As far as printing.....What printing? The shirt has a sort of thin foam sewen into the outside layer of the pocket. This breaks up any hard lines and printing from the firearm.
In my opinion the shirt is AWESOME! Very comforable, Affordable, and Versitile. It is important to remember that this is a deep concealment application, and draw time will definately be less than an Outside the Waist holster, and Inside the Waistband holster, and Shoulder Rig. However, it is not so slow as to be an ineffective means of carry.
I found that the shirt pairs best with the 5.11 Tactical Covert Carry shirt. This shirt has quick pop snaps in strategic areas to allow very fast access to whatever you may have under the shirt. The top button is a real button, then two snaps disguised as buttons, then one more button and two more snaps. It also has 3" velcro closures at the bottom sides of the shirt to allow quicker access to a belt mounted holster.
Hope that helps ya out. I have been testing this for a few days so far and have yet a few more left. I will also get some pics up for everyone. Cheers and Enjoy.
