The little 9mm bolt has a lot shorter stroke.
Everything is relative.
When I shot Expert with an M-14 many long years ago, I noticed that, due to the recoil, I had to recover my sight picture each time I fired a round. Recoil problem also made the M-14 nearly useless on full auto, unless the soldier really wanted to shoot a lot of holes in the sky.
As an aside, my Kindle’s auto spell somehow interpreted a,misspelled “recoil”as “bacterium.” Please don’t ask how; I haven’t the faintest idea.
