Agreed, especially if wearing gloves, it's difficult to go lower without unintended discharge. I like to feel the trigger before it goes off and know when I'm pulling it. Yes the sonic brass cleaner doing well. I love the job it did on my filthy AR parts! I am still thinking of getting the other rotary you mentioned to get the brass shiny though. The sonic did a great job cleaning even the primer pockets with 2-3 cycles, but definitely not near as shiny as the other media tumblers.
