It was hard for me to see your results but it appeared that the 48 shots where a bit higher? This is the same type of result I got from similar pair drills. The 43x is snappier but for me it would come back to zero very quickly and provided better hits but felt harder to control due to a little more recoil. I think that what seems to be surprising to many is the 48 “feels” like its slightly less recoil but the 43x appears to come back to zero quicker. My drills were 10 yards so my splits weren’t as quite as fast, they were high 20’s low 30’s. Shooting the 365 XL for me was even better results and not as much recoil but still came back to zero quicker. No way to tell without a dot but the recoil arch I would guess is less. At 10 yards I was able to consistently perform a bit better with the XL then either of my glocks.
