The "Ayoob Files" in the July/August American Handgunner throws some valuable light on the holster controversy.
It's the story of a 71 year old retired Marine who took on two armed robbers in a Subway.
After the criminals got the money( including the Marine's wallet), they forced the store manager and our hero into the backroom. The Marine instantly recognized the danger and looked for his opportunity to defend himself.
He was able to draw his .45 Para, kill one robber, and sent the other cretin fleeing with a slug in his chest.
The good guys won that round even under adverse starting conditions.
What caught my eye was the "tactical rig" the Marine was using to pull off this victory.
"A cheap nameless cloth holster [worn] near the middle of his back."
