like I said earlier ... too bad you are hung up on the 1911 frame
if you really aren't hung up on a 1911 frame then get a Glock.
as mike said it is much much easier to clean
Today I finished reading the Gun Digest Book on the Glock written by Patrick Sweeney.
what I was rerefreshed on was that for competition Glock makes the G34 in 9mm and G35 in .40 - why - because of the ISPC BOX. longer slide and longer sight radius helps in competition.
Also the polymer frame absorbs more energy of the recoil than a still steel frame like the 1911. Also since it is for competition the 34 and 35 have a better cleaner trigger.
