The 1873 and 1892 are pretty speedy. I live about 6 miles from the Single Action Shooting Society Founders Ranch and these folks could have laid out all the “fast guns” of the west with no problem.
This yahoo probably was slow, but a lever gun is fast in the hands of an expert.
I used to have a Browning model 92 in .44 mag. It could be reloaded quickly tho it would have been rough on the thumb.
In a shootout I doubt if you would even notice.
