That’s interesting. I don’t know squat about this stuff, but it seems like if the RSA had that much effect on ejection pattern, then different ammo, (standard vs. +p+), would show different ejection patterns too, but obviously not. Like you said it sounds like it just took the right combination of components.
It's easy for some folks to forget (or overlook) that compound RSA's are really
assemblies, and if any of the parts used to make them may have a tolerance or QC issue it may lend itself to a head-scratching functioning issue.
Kind of like how magazines are
assemblies, albeit you can replace parts in them, if necessary.
Sometimes it may be easy to forget that magazines and recoil springs (and especially compound RSA's) are at the very heart of reliable, optimal pistol functioning.
The
ejector is the other half of the "timing dance" when it comes to extraction and ejection, with more attention often seeming to be paid to the
extractor.
Some of the gun companies have designed ejectors with longer tips (usually described as providing for "faster" ejection, or improved ejection with higher pressure loads that give a faster slide velocity), as well as refining and tweaking the angle of the tips where they contact the case base.
One of the things that can frustrate some owners/users is that the "shooter variable" (think grip technique stability) can have a strong influence on functioning, as different shooters may vary in how well they can grasp and stabilize the frame during cycling (and not allow their grip/wrist lock to "rob" force from the recoil spring). Then, there's the potential for any particular shooter's grip technique to vary, depending on the conditions at the time, including shooter inattention, injury, etc.
