If you’re going to bayonet people, a Mosin-Nagant would seem to be nearly the ideal choice of weapon.
The nearly two-foot long blade of the Model 1891 M-N rifle is a close followon to those of the Revolutionary War Brown Bess musket and the Springfield and Enfield rifles of the US Civil War. It was in no way advanced or modern, even for 1891.
But for poking right through a heavy padded wool overcoat, probably wet and covered with leather bandoleers and straps, snd skewering the contents therein, coming out the back, it does a pretty good job.
Just for fun, I welded the blade of a $10 M-N bayonet to the handle of a $10 Romanian AKM bayonet handle...and waited. One of the local cops knocking down free-refill McDonalds coffee was bragging on his taxpayer-provided $400 bulletproof vest, when I said my AK bayonet would punch holes right through it. We tossed it over a range target frame, and I went at it. Poked right through, front and back.
