Admin reload...I taught basic pistol courses for many years and still don't understand the purpose / intent of this idea. We only used:
Clearing / unloading
Regarding reloading vs tac reload, I see advantages to both. I don't favor the idea of ejecting a partially loaded magazine to the ground in the dark where it may go down a street drain, into bushes or whatever but I understand the logic behind the idea of getting the gun topped off as quickly as possible. I also understand the possibility of fumbling the tac reload as I try to juggle to mags in my hand at once. IMO, practicing these procedures gives one the best chance of success...whichever one you choose.
