LOL,one of the local county mounties carries a 1911 with a 30 round mag.
triple stack? fingers that can palm a basketball? or just really long?
those glocks have 33 round magazines for most calibers too

but they're a bit LONG.
i have a 1911-a1 with match grade components. it's verah nice. it IS one of my favorites.
>>> pros: very solid. very accurate. night sights even. cool: 1911 100 year anniversary. quite slim. TIGHT construction. big bullets. very well made.
>>> cons: heavy (though not as heavy as my .22LR pistol); only 8 rounds but i have 4 spare magazines
>>> very expensive new $$$$ this one unless you get a very good deal walking in the store needing cash now and you intercept ;D
springfield armory makes a 1911-esque gun in .45 that holds 13+1 without magazine extenders/etc due to the double-stack which makes them not quite as slim; polymer frames as well. IDPA/IPSC match grade ready shooter with adjustable sights, typical price is around $750; or choose 9mm (19+1 !!) or .40 (16+1 !!!) if you want. see the hickock45 videos on this gun. i'm very excited about these. official springfield armory spc sheet:

they also make '''The Springfield Custom Professional Model 1911A1 pistol is produced under contract by Springfield Armory for the FBI regional SWAT teams and the Hostage Rescue Team.[17] This pistol is made in batches on a regular basis by the Springfield Custom Shop, and a few examples from most runs are made available for sale to the general public at a selling price of approximately US$2,700 each.''' oogly moogly
moose said "greatest handgun creation ever made"... that's a big claim

most of the .45 shooters i talk to always quip "one shot, one kill". well, not so much. i know the history of 1911 and the reason behind it with the unstoppable murderous moro :> from the wiki:
http://en.wikipedia.org/wiki/M1911_pistol
'''In response to problems encountered by American units fighting Moro guerrillas during the Philippine-American War, the then-standard Colt M1892 revolver, in .38 Long Colt, was found to be unsuitable for the rigors of jungle warfare, particularly in terms of stopping power, as the Moros had very high battle morale and frequently used drugs to inhibit the sensation of pain.'''
now, in what situations would one encounter someone who's tolerance to dying via drugs was common?

seriously, imagine someone taking .38 several times and refusing to fall down? nice. ever read the about the peter soulis incident? no? this dinosaur wasn't even ON drugs, yet he KEPT GOING far beyond what you would expect someone to do:
http://www.lawofficer.com/article/training/officer-down-peter-soulis-inci wow is all i can say.
so for survival, the gun you have with you is the gun you need to use to survive. to fight your way to a 1911 of some kind, then use that to fight your way to your battle rifle

escalate! brains molon labe zombies!
