I had a pre-ban M11/9 & it was very unreliable. Even if it had been reliable, it's ergonomics were awful. Because it's barrel was so far above the grip, it's recoil rotated the gun in your hand significantly resulting in inordinate muzzle flip for a 9mm.
I traded it in and got a Glock 26 and stuck a 33 rd Scherer mag in it for those times when I want that high capacity gangsta' image. It works like a Glock, that is to say great!
