A few years before I retired in 1997 we transitioned to the Glock 23 and I earned to handle it like a natural extension of my arm/hand. Recently swapped my Gen 2 G23 for a Gen 3 G17 b/c the 9 mm is cheaper to shoot and recoil is lighter. My plan is to use the G17 for LEOSA qualification this summer. While I considered other brands I also thought about the old dog - new tricks thing and stuck with what I knew.
