1911 lowered eject port

gotstolefrom
The 1911 45's I've had all had the lowered eject port.
I'm looking at a sweet deal on one with the "non-lowered" eject port in the slide.

I can 'imagine' that some eject problems could occur with the 'standard' eject port.
What are the drawbacks to the 'standard' eject opening ?
Or, when and why did the lowered opening become more SOP ?

Thank You In Advance

    I believe that the lowering of ejection ports began due to brass getting dinged up when leaving the gun, a trait that reloaders hate.

    Most competition shooters reload and someone ( back in the day) probably put a high speed camera on a cycling 1911 and found that the brass was getting bent from hitting the port on the way out.

    Iam sure lowering ports also aids in reliable cycling of the gun by lessening stove-pipes, but Iam pretty sure reloaders input had a lot to do with the trend to lower ejection ports.

    I remember seeing lowered ports as far back as the 1984 World Speed Shooting Championship "Steel Challenge". Some folks were possibly doing it before then.

    A lowered port is always beneficial. Not only does it help from beating up the cases, it makes it where you will have far fewer "stovepipe" jams. There is NO reason to want a semi auto without the lowered rjection port.

    As to when the lowered port bedan, I purchased a 1911 Colt combat Gov't model in 1983. The lowered port was one of the "combat" modifications. Colt initiated these changes because they were changes that most serious shooters had done by gunsmiths.

    The Gold cup was first Factory Colt with lowered port. It does improve function does not ding the case mouth as ofter and lets you tune the ejector so the empties go out the side[^][:p] instead of out the top and DING the shooter between the eyes[:0][:(!][V][xx(][:(][:I]

    The enlarged ejection port helps the gun more readily operate with a wide variety of ammo and allows you to mount a scope. It will also help keep you from getting the occasional brass strike to the forehead because the gun can be set to eject the spent case out of the port lower and more to the right. With full power ammo, proper recoil spring and properly adjusted extractor and ejector the small port works just fine and has been doing so since it's adoption in 1911. I have Colts with both port sizes and trust them equally with my life.
