I was holding out for the Jerry Springer show, but I suppose I can discuss this here, in private ...
I wear Thunderwear. Yes, it's true. But, the reason I continue with this behavior is because I've found the solution to the Thunderwear, uh, blues.
First, don't wear it the way they tell you to wear it. In my case, the butt of the pistol won't stay under my belt anyway ... it slips down. So, I wear the pistol in the right pocket of the Thunderwear, but I wear the Thunderwear almost on top of my left leg (the right, angled side of the Thunderwear is parallel with the inside of my left leg). This accomplishes a number of things.
First, back to the title of this thread, it keeps everything out of the way when I have to use the rest room. Doesn't matter whether I'm using a stall, urinal or trough. The pistol is to the left of my, uh, manhood.
And, when I sit down, instead of the pistol and Thunderwear tearing out my pants crotch (which happened, when I wore it in the middle), it just lies flat on top of my leg. If anyone notices the 'bulge' (and no one has ever mentioned it), then I suppose it just enhances my, well, reputation.
Access is not great with this rig, but compared to the other difficult choices for deep concealment, it seems reasonable.
Hope this helps you. One thing I have learned from TFL ... you can research carry options, and it certainly helps. But, at some point, you simply have to spend some money and try it out for yourself. Everyone is different, and often, experimentation is the only way to come to a conclusion about what will work for you.
Good luck. Regards from AZ
