drop the hammer 

Holding nothing back. Usually refers to ending something.

The term comes from the hammer action on a gun. The hammer dropping on many pistols is what causes them to fire. If you "drop the hammer" on somebody, you go all out.

drop the hammer 

An idiomatic expression meaning roughly "to explode in a fit of rage and fury", it is derived from the action of a firearm hammer "dropping" -- or striking -- the firing pin which in turn impacts the round and causes the mini explosion that results in a bullet or other projectile being launched at a high velocity out of the end of a barrel.

The expression can be used in several different variations with the above definition: 1) ...part. in a draconian way 2) ...leaving a wake of destruction in its path 3) ...against a very specific target with precision; etc.

"I have a clear shot of the target. Requesting permission to engage."
"You have the green light. Drop the hammer on that motherfucker."
BANG. Bad guy fall down.
