They’ll be coming with guns out

The speaker (contributor’s mom) was referring to Republicans when she heard that an impeachment inquiry on Trump was starting.  This is a mashup of “with all guns blazing” (forcefully and with a strong sense of purpose)  and “knives out” (people eager to criticize another).  Perhaps in this era “guns out” is more appropriate than knives.  A big thanks to Sandor Kovacs who heard this one and passed it on.
