I gotta disagree with you on this. I think they’re a pretty damn clever invention.My personal opinion is binary triggers are sad toys for failed 'operators' begging for their first negligent discharge.
Unlike bump stocks, you can actually hit your target with a binary trigger.
As a matter of fact, I’ve run a .22 with a binary trigger before and for long distance shots, the “fire-on-release” shots I took were actually more accurate than the traditional “fire-on-pull” shots.
As far as them being dangerous, as long as you’re following the basic rules of gun safety you’re all good.
