If you don`t mind I`ll add to your ejector question so we can all get smart.
If an extended ejector is added to a gun wih a standard one, should it be trimmed to the same dimensions as the original? Gun has never "smokestacked" a round, So, if it is changed, trim the extended to the same size, or leave it as the shape it comes? Thanks.
not trying to be a wise ass here, but regarding Greg D.'s quetion - if you install an extended ejector and trim it to the shape (i.e. length) of the original, i don't think you've done anything but swap out a part for what is now its twin. Only reason to do this is if the original ejector is substandard metal (i've seen this on cheap Century Arms 1911 clones).
Only reason to install an extended ejector (as I understand it) is to resolve some ejection problem after you've looked at other less invasive fixes like tensioning your extractor, and perhaps before doing more drastic changes like (additional) lowering of the ejection port. Installing an extended ejector into a gun that works okay probably won't do anything besides:
1) produce ejection problems
2) prevent you from easily ejecting live rounds
