Nice read Hickman. I can't disagree with this logic. I have often wondered this myself. Why would I need to reload the gun?
1) gun is out of cartridges - no reason to retain the mag
2) gun malfunctions - could be a bad mag so why retain it? Of course that assumes I happen to have a spare mag.
3) lull in action - that would be hard to determine. What I want is more rounds in my gun as fast as possible with as little requirement for fine motor skill as necessary. Hopefully I don't need more shoots later. Of course a person can pick mags up off the ground.
I admit I don't practice my tactical reloads as much as I should. Usually I just release the mag and then insert a new one. No rushing the process just hit the hole and run the slide.
