whats your definition of "full size"... most duty pistols have roughly a 4 inch barrel... would you consider that to be full size?...
umm.. i like the 1911 for a couple reasons... im not going to use some lame line youve heard over and over again like "b..b..but the military used it for so long".. because that has no bearing on my decision...
i like the 1911 for carry for one, and this can be applied to other handguns as well, but its single stack.. with slim profile grips, the double stack frame is pretty slim...
second, i like the single action only trigger... less fewer parts, simpler mechanism, seems to be more reliable than many others... and you dont need a safety.. a DA/SA goes off if you pull the trigger, as do the glock triggers, DAO... but with the 1911s, if the hammers down its pretty much safe... and its a quick, simple, fluid motion to cock the hammer while drawing it... where most handguns that one action while drawing is disengaging a thumb safety
i like handguns that point well, for CCW you may.. and you may not have teh time to actually aim.. since most CCW issues are such close range, i like something that points well for instinctive shooting without sights..
and lastly... i dont like plastic grips... if your hands are sweaty, or you sweat it can make the grip feel slimy
