I like the lighter recoil of the 45 but would use it at a reduced range than the 44. I also think a faster follow-up shot may be possible with the 45 due to the less recoil, but have not timed it--and with the reduced range, hopefully this would be less likely to be needed. I know the 45 can be loaded up, but I don't since I have guns that can not handle those loads, so for me if more power or range is needed the 44 will win out. If that is not needed, I prefer the easier shooting 45.
