Seriously, enough of this 'one or the other' stuff - I figured it out. The M1 Carbine is going to be my BACKUP rifle for working mall security.
Between your MBR and your pistol, you have your BACKUP rifle, get it?
Everyone always talks about a backup pistol...
Only problem now is finding a sligning solution to carry both at the same time so they don't bounce into each other when I scale and rapell buildings during high-risk retail entry. Would help if it looked stylish - because I'm not always in high-risk situations, you know.
OK, so I'm 220 lbs, so I can probably carry:
-M1A (4 20-round mags and a bandolier)
-M1 Carbine (+2-30 rounders +4-15 rounders, bandolier)
-Valtro and + 2 mags
-P32 and 1 spare mag
-IR Goggles
Darnit... where's my Blackhawk catalog?
What's that sound? Is the sky falling?
AHHH!
Seriously, For CQB in CA, I'd be holding the Carbine with a 30-round USGI mag with a fresh spring, stoked with Georgia Arms hollowpoints, with the Valtro ready in the holster and the M1A on my back. Better yet, a shotgun.
Of course, I would do all this in style, wearing the latest in 'low drag' fashion from the designers you all know and love. After saving dozens of lives at the Mall, I'd pull out my carbon fiber kevlar-plated cigarette case (yes, the one that saved my life momentarily before by taking a bullet) and...
...wake up in my bed, to my alarm clock. It was all just a dream.
