I prefer a good DA/SA for carry. However, I've practiced often to get very proficient with the DA pulls on the Beretta's I own. The PX4's have a very nice short crisp DA as opposed to my longer DA on my 92, but I shoot them all well in DA to SA. If you practice with DA/SA it will become consistent for you. With a 5.5 pound trigger pull your only a pound or two away from carrying(especially IWB) a SA 45 Cocked and Unlocked.
