-Manual safeties on handguns, can be in the wrong position at the wrong time and get you killed with an AD or get you killed when the gun doesn't fire.
It never ceases to amaze me that the folks who worry about "forgetting" their thumb safety on a 1911 are going to "remember" to keep their finger off the trigger when they don't want to shoot. I am sure that for Sean, myself, and other ardent 1911 shooters in this thread, we catch ourselves from time to time swiping safeties off on other handguns that don't have them. On the draw I have swiped revolvers, an XD I tried, and once, just once, swiped the pistol grip unconciously on an AR-15. I didn't believe it, but my friends and I were videotaping and sure enough, I'd done it with the first mag eventhough the AR was off safe and already pointed downrange after charging.
-Don't care for the feeding characteristics of the .45 ACP in JHP and I think the FMJ .45 is a very overrated stopper. I think a handgun needs speed in it's round not mass to be effective.
JHP feeding problems are overstated in modern 1911 pistols. From mags that seat the round higher relative to the chamber, ramped barrels, and essentially factory ramped and throated set-ups from everyone else=problem solved.
As for mass versus velocity in a handgun round, there are literally thousands of dead guys killed by Thompsons, Grease Guns, and 1911s who'd disagree mightily about the effectiveness of .45ACP FMJ if they somehow could.
-Only 7+1 rounds is way too low, you might as well just use a revolver and be done with the hassle of trying to feed that big bore JHP ammo.
There is no feeding problem, but as an aside, one can readily go to 8+1, 10+1, or even 14+1 thereabouts and still have everything a 1911 is famous for. BTW are you going to establish your own "beat zone" of suppressive fire on the street or something? A civilian self-defense shooter "owns" every bullet launched. As a civilian, if 7+1 can't get it done, chances are you are going to prison or the morgue. One thing is certain, you can't find or carry as easily a revolver that equals the power and flat concealability of a Commander sized 1911.
Which is of course why the CDP class .45ACP 1911 is as fast or faster than all other times at the IDPA nationals for SSP (Glocks), and SSR (revos). Only the ESP division, filled with SA 9mm "gamers" armed with pistols that not many with sense would rely on in reality, come close.
-Cheap ones are junk, good ones cost an arm and a leg.
Cheap ones can be junk. Good ones are cost competitive with anything on the market. Exceptional ones cost and arm and a leg.
-Have to be too loose to be reliable, have to be too tight to be accurate.
Pure misconception. It is not the slide to frame fit that determines accuracy, it is the quality of the fitting of the barrel lugs to the lock up cuts in the hood and the fitting around the muzzle and the slide or bushing that determines accuracy. Again, in non-.22 accuracy competitions, the contests are dominated by 1911s.
Got any more howlers?
