As much as I like the 45 and the 40 the 9mm is much better recoil wise and much easier to shoot and make multiple hits in a short time frame. With today's ammo, I'm not sure the 45 has that much over the 9mm as a defense carry round against humans. The Glock was built and designed for the 9mm and I believe the Glock is most dependable when chambered for this round. The Glock 19 hides as easy as most compacts with the right holster. For a carry pistol and easy to conceal the Glock 19 rules the roost.
