I've taken my Springfield 1911 to the range three times for function checking since EGW fitted a 9x23 barrel in it.
I put a box of CP FMJ competition and a box of Winchester Silvertips through it.
Even with a brand new, still in the shrink wrap, 22lb Wolff spring the brass is VIGOROUSLY ejected. Nothing like a .45 which can be made to drop the brass three feet to the right and one foot to the rear simply by changing the recoil spring.
I don't think Wolff makes a spring heavier than 22lbs but the way this 9x23 operates it seems like a 26 or 28lb spring would be needed to tame "the fickle flying brass".
I wonder if the amount of tension on the extractor has anything to do with how far the brass is tossed? I sorta doubt it.
Maybe the ejector is too long and if I trim it back to minimum length the extracted brass won't get smacked quite so hard. Any thoughts?
