My new build, 1911, 5 inch, 45 ACP, has never ejected correctly.
The failure usually leaves the expended case on the breach, held there by the extractor, with the trigger in half cock.
Dropping the magazine and pulling the slide back, drops the case through the empty mag pocket.
I'm using a Wilson extractor, a Swenson oversize FP stop and Wilson Ejector.
This failure occurs with several manufactures ammunition and Wilson recoil springs from 10#, 13#, 15#, 16# 1nd 18.5#.
The original thought was weak ammo, too strong recoils spring, guess I've funded Wilson Combat with my flailing.
Been through 2 "factory" extractors from Sarco, went to the Wilson combat.
Bought The Wiegand extractor tension gages and use them with my trigger pull gauge. Image attached.
I'm now thinking that I may be short stroking the slide since the failure mode is consistent and the case drops once I pull the slide back when clearing the failure.
This thinking drove me to the extra-long ejector, now I' wondering how to tune this part correctly.
I attached some pictures, one with marking showing where the slide is when the Wilson Ejector first contacts the case and a second mark indicating where the slide is when the case is ejected.
The picture with green masking tape has marks showing where the unmodified Swenson XL ejector contacts and ejects.
My question is how much should I shorten the Swenson Ejector for a first pass iteration in the testing process.??
Thanks in advance...
