I built a new .38 super with a Caspin Slide & Frame. It is accurate as all get out but the dang thing is killing me on ejection.
I have two extractors, Ed Brown & Wilson, tuned to death to no avail.
Ed Brown ejector and Fusion both perform the same.
Used every spring from 12 - 22 problem is minimal at 16-18.
Metalform, CMC and Wilson mags all feed fine, no issues.

It will throw brass every direction and crimp the mouths, see pic. One kicked over 20 straight away today and others went left and right and behind. I am losing my marbles on this one, first 38 Super maybe that is it.
Just from the looks of the cases and the 2 damaged areas on the casemouths, it looks like the case is not clearing the ejection port and is being pinched between the barrel hood and breechface as the slide returns to battery.
Is the forward-most point on your ejector nose at the top of the ejector as shown here in red?
If so, make it look like the green one and see how that works.
Port it, or put in a longer ejector.
The ejector is as shown in red, I was marking the case to see were it was hitting. Looks like it is above center I will adjust accordingly and report back. Thanks for the input.
It works!
I tuned the ejector as shown in the diagram and she is kicking the brass out ding free. First case goes forward and the rest pile up 3 feet to the right. Not sure on the first but they are all free from damage. I will see if it needs a bit more tuning, kinda hate to touch it now that it works.
I was almost 100% sure that would do the trick, but beyond that I'd just be guessing as I've got no experience with Super 38 ejection.
First case is going forward because it's being smacked by the breechface but the case mouth is above the level of the hood. No idea why, however.
I had noticed the same first round ejection difference with my 38 super Commander. It took me quite some time before I found that it was caused by loading to the max of 10+1 and the top round was pushing up so hard on the disconnector rail that the slide velocity was much slower on the first round. I tried different mag springs and got rid of the first round difference and created last round problems. So I just live with the first round weak ejection because I need 10+1 capacity for IDPA and USPSA .
I would apply tungsten disulfide (powder) and oil the rail. That might do it for you.
Did you mean molybdenum disulfide?
Tungsten disulfide is also known as Danzac and is used by some as a bullet lube in lieu of molybdenum disulfide. So I would consider it possible that he meant what he said.
Strange as it might seem (to those who know me) what I meant and said were correct. WS2 (don't think I can do subscripts here) has better properties than moly. Long ago, I became prejudiced against moly, I don't remember all of the reasons.
Wolfram disulphide can be effectively applied by hand or by air blast. It loves oil, and goes away when unwanted (it hates soap/detergent). It is a bit more expensive than moly, but a pound will last me probably longer than I will.
Aftec extractors work really well with supercomp brass. You have a 38super size case with a 9x19 rim extraction area without the tapered case, they need all the help they can get to extract consistently.
You might also try a EGW flat firing pin stop with a 1/16th radius cut in it instead of the normal ski-slope. Slows the slide down a bit and empties usually dump within three or four feet.
