FLETC went full boomer and protested against the use of agency issues RDS-equipped pistols by students during the basic courses (CITP and UPTP) because of a dramatic difference in qualification scores, which ended up making the task of achieving a perfect score almost trivial. Maybe that's an overstatement, but I remember hearing it was a night and day difference in scores between students with RDSs and students without, to the point that FLETC protested that its unfair to other students and they shouldn't be allowed to use RDSs during the basic courses. I believe the "offending" agency was HSI.

Gadfly was detailed to FLETC as an FI during this time, he might have more concrete data on the scores.
