" The stats and abilities of Exalted weapons are directly tied to whatever weapon (and mods equiped to said weapon) you have in the relevant slot (ie secondaries for Peacemaker, melee for Hysteria/Exalted Blade, primary for Artemis Bow, etc)."

This is wrong. Exalted weapons have their own set stats, and are functionally the same as equipping an entirely different weapon. The only things that carry over are the mods. The base stats of your equipped primary/secondary/melee have absolutely no effect on Exalted weapons.

" Please, don't give answers to questions you don't know the answer to."

Follow your own advice.

To answer OP's original (although old) question, Mesa's pistols themselves will not activate the buff. However, if you use the Dual Toxocyst to activate the buff, then switch to Peacemaker while the buff is active, it will carry over.
