We got to drop the whole multiple gun thing, it just isn't practical, you can basically reload your single pistol in the time you get your new ones out. And if your face to face with an enemy and your out of ammo, RUN and get to cover where you can reload safely then shoot back.
If this was real war you could just throw shit at him. And that video was a pretty good indication on how to reload as fast as possible, build yourself some magazine holster thing that holds the mag out at your front and you can grab it real quick to reload.
All that money spent on holsters and guns just to save what? 1 to 2 seconds?
EDIT
Oh and about the rubber things shattering on hard contact, well I didn't know they do that because of my lack of experience so that basically destroys my idea.
