My main carry gun is a Glock 22, however I also have a G27. I've been shooting about once a week lately and mainly using the G27. My theory is that improving my ability with the G27 should make a more noticeable improvement with the larger and easier to shoot G22. Does this make sense? Or am I wasting practice time and setting myself up for failure? I still shoot both, but many more rounds through the G27. I'm just trying to optimize my training time/ammo and I'm curious as to whether I'm just tricking myself.
