No one else is bothered that LEO's are provided a gratuity/discount that is not available to the general public?
Somewhat, but not a lot. If it was for a rooky just out of the academy, I would say fine give him the discount, but for a 10 year veteran on the force, I would say foul he should pay the same price as me for a personal weapon. Departments don't generally buy their firearms from a local gun store, not large departments.
Most advantage for a LE is that there is no waiting period to pick up a handgun, they can purchase and walk out the store as soon as the proper paperwork is finished.
