One of the reasons I like the 1911 is the simplicity and robostness of the design. I'd have to do a lot of paper punching with this setup to convince myself that it's a good thing for defensive purposes. I know FN has had this design for 20 some years, but I have never known it to be adopted by any military or le units, and I have never seen any durability results. Not saying it's bad, just being cautious.
