Its probably going to be entirely luck based.
Indeed this. Not all the DLC weapons had a related achievement in other events.
realy? let's look in past:
tommy gun has achievement
buzzsaw has achievement
flare has achievement
scythe has achievement
dr.t's lds has achievement
mcz thrower has achievement
s.p. musket has achievement
orca has achievement
-----------------------------
all weapon from community packs had achievement.
the only weapon which didnt have achievement was R.S. Tommy, but i dont consider it as dlc weapon
