Question for Tuner

[1911WB]

Just replaced the extractor (Wilson Bulletproof) & the slidestop (Brown hardcore). I had to slightly "tune" the extractor as it had very little tension as received (also did a very light stoning job on the extractor). Otherwise everything dropped in and worked perfectly- feeding & extraction/ejection was perfect in this morning's range test. However, the ejected brass had very dented mouths unlike before the new parts when fired brass was in pretty good shape. Now the stuff is still reloadable, but ugly! Why whould a new extractor or slidestop cause this? Well, I guess I have to have something to complain about cause the new pistol is perfect other than that.

Howdy WB,

What's happening is that the case is kicking out at 3 O'Clock...or lower...and is hitting the bottom of the ejection port.

The Wilson Bulletproof has a "square" hook, and most require a little
radius on the bottom corner to change the release point of the case.

There could also be a difference in the length of the hook from the tip
to the wall...where the case rim gets its tension.

You can also tweak the ejector to change the angle of exit a bit...but
if you have a standard GI-type ejector, it's limited. An extended ejector
can be undercut slifhtly at an angle to kick the brass out at a different angle...Rule of thumb is: The higher on the rim the ejector hits, the more straight up the brass flies...The lower it hits, the more straight out.
In your case, a light undercut angle on the bottom to raise the point of contact would help get it over the top of the bottom of the port. EASY! A tiny bit goes a long way.

Basically, tuning for angle of ejection is a trial and error "zen" thing, and
different pistols will produce different results for a given tweak. Be
prepared to kill an ejector. Sometimes it happens. Ask me how I know..

If you have a private place to shoot, or a fairly tolerant range, you can actually work on the extractor and ejector at the range so you can check results immediately without needing to much of that "zen" thing.

California and sneezed over the San Andreas fault and got swallered up
