Wrote this up on discord, figured I should repost it here to give people and idea of what they're getting into, big fan of the mod btw.

Changes:

Deagle: 20% more damage, 65% louder
M1911 33% more damage, 96% louder
M9 87% more damage, 125% louder
M625 23% more damage, 96% louder
Magnum 13% more damage, 27% louder
M36 58% more damage, 544% louder

By loud I mean tiles affected, so something affecting 9 tiles would be 300% louder than one affecting 3.

So yes, firearms b41 guns do deal more damage than vanilla, but while Britas makes the guns quieter, b41 makes them louder.

I dunno how to measure accuracy or aiming level requirements though, would appreciate it if someone could help there."
