As much as I love the beautiful chunk of steel that is the 1911, there are logistical issues with fielding them.
I agree that we wont see 1911's again, but not for logistical reasons; unless you're talking about inter-mixing them with M9's. The 1911 is generally easier to work on than the M9 and has a much longer service life; the logistics would be easier if you ask me.
