Of course there are “long term professional shooters” that have never DQ’d.
There are also C class folks that can’t keep their finger off the trigger and the muzzle pointing downrange at any speed.
The trigger pull weights of either of the aforementioned competitors would have little bearing upon their likelihood to DQ. You’re going to see 180’s far more than you do ND’s.
The top level competitors also have much better bearing on their physical limits and don’t often exceed them at major matches. Can’t say as much for a lower level competitor in my experience.
I’d be far more inclined to wear a plate carrier RO’ing a local club match than I would the super squad at a USPSA major event.
Stop trying to blame gear for shooter incompetence.
