i believe despite the drop in trigger pull weight, this system is every bit as safe as the original Glock trigger setup. With the current situation and the 320 triggers, I highly doubt Glock would release anything that would be less safe mechanically than the standard trigger. I suspect this performance trigger has had the hell tested out of it, knowing Glock.
My money is also on the fact if these do prove to be popular, this will likely become the factory Glock trigger system across the entire line the near future.
