Setting up mini gun?

in Equipment
Newbie question (and yes I searched) I'm getting a touch up gun to use for my activator, as my compressor is small and I only using it for spraying activator, anyway I did some research and what I've found kinda confuses me. With a regular gun they say so set it up with a 1.4-1.8 tip. I've read that the touch up or mini guns it's a different tip I'll need because the gun and everything is smaller? Is this true and has anyone set up a touch up gun for activator? Sorry if it's a stupid question. I'm trying to get out of using the spray cans of activator and still confused if I should use a hydro vator or regular activator.. Any input is appreciated. Thanks!

as far as activator, hydrovator is a crowd favorite as well as k2 brew and a couple others. pick one, use it, learn it, then try something different if you want.
practice practice practice...
good luck
