I personally do not like any pistol that has the mag catch at the butt. This takes two hands and sometimes your eyes as well to operate.
No argument there...not to mention the fact that Murphy's Law specifically states this type of mag catch will somehow mystically and magically find a way to snag on something and release the mag all by itself as the piece comes out of your pocket!

That 'small' detail aside, I'm thinkin' this might be a good option as a carry piece in the summer when ones clothes won't/can't help hide something larger.
