IMO the Glock 34 is the ultimate choice for USPSA Production class and IDPA SSP. I've got a 35 (used to shoot limited class with it) and it's a great gun. The 9mm would reduce your splits over the 40 though. All in all a great gun, fits the box, 3 1/2 lb trigger that's consistent (as opposed to double/single action), good sight radius, reliable and comes with a durable finish! The 34/35's are also great carry guns.
