Shorty,
Sorry! I had not thought to check back on this thread since I posted.
For me, the Kangaroo Carry holster is not as easy to draw from as an inside the waistband holster, but it very useable, and like anything it gets much better with practice. I use this primarily when I want deep concealment, and NOBODY to know I have a firearm. It is really a nice design. I hope to never, never need to draw it to protect anyone, but am confident it will do the job well if the need ever arises.
I just bought mine last Fall, so have experienced it in higher temps, but I suspect it will be a little hot. The days I need it, though, I'll be wiling to put up with that, I think.
Good luck in your search!
