You've all seen shooters who are "going hot" (on the range) selecting a magazine from their rearmost pouch, rather than the front pouch. In Rich Grassi's article Editor's Notebook: "Tactical" Reload in the May 13th The Tactical Wire, he says: "...Per my training, I always used the least accessible magazine for the tac load, saving the nearest magazine for those inconvenient emergencies..." Later, in the same article, he says: "...I stowed the depleted magazine in the least accessible pouch - but still in the pouch, not a pocket. As there were only three magazines, I'd rather reach for the pouch (if needed) than to engage in the "ballistic Macarena" (coined by Mas Ayoob) - patting myself down for that last partly-loaded magazine..."
I used to draw from my rearmost pouch myself, as a matter of routine. Now, I think that it's a training scar, and that it's probably a better general practice to:
a.) draw from the most-accessible pouch;
b.) use magazine pouches to hold only loaded magazines, and;
c.) stow partially loaded magazines somewhere else, to avoid any confusion.
What do you tell your students?
