Les Baer failing to eject.

Hi All.
Recently purchased used Les Baer frame mount and it started failing to eject with spent casing becoming lodged on ejector. New cartridge below spent casing trying to feed.
Had local gunsmith work on pistol, but still having same issue just less often. He said he modified extractor and cleaned her up some.
Any ideas in how to proceed next?
Thanks.

Load info?

Keep it clean and apply oil liberally.  That's what I found when experiencing the same problem.  When I inquired to Less Baer about the problem after friends recommended more oil the response was "We recommend that all of our pistols be very lubricated at all times."  

Oh, it may be the extractor, the magazine, the recoil spring, the load or even your grip - but oil is cheap and easily applied.   After making it a practice of oiling the gun much more than I would have thought to be reasonable all my problems went away - well, all except those of X ring aversion, which I am working on - the damn thing is just too small.

4.3 be with 185 Jhp or lswc 185 with 3.9 be are my loads.

Does it with all 6 mags I have including two that came with pistol

Probably needs more extractor tension. That load is plenty hot enough and its a frame mount.

I had the same problem with the same gun. KC asked me when I last put a mainspring in it. I answered, "never". Put a new 20LB mainspring/hammer spring in. Works fine now. I shot that gun 8 years before replacing it. And I shot it a lot. Hope this helps.

Same gun (but now running a slide mount) and for me it happens in two situations, low power loads in the cold and used Starline brass.  Mainspring is fresh (19 lb) and extractor was tensioned with a Wiegland fixture.

incidentally, all LSWC shapes are not alike.  The Magnus 811 I use has more case volume.  The 811 with 3.9 N310 is the load that mentioned above which hangs up in the cold.

EDIT:  I found the Ed Brown springs sold as 19 pounds are 22# on my tester (and much stiffer than what I took out).  I swapped the softer mainspring back in this weekend and there were far less FTE's when cold but as the slide wasn't 100% locking back I need to do a bit more experimenting to get the spring balance for that load.

1. Does it fail to extract if that were the only round in the mag?
2. Does it fail to extract if you load round in chamber, then remove mag?
3. Does it fail more frequently if there are more rounds in the mag?
4. Is spent brass hanging up on the scope mount? Look for a shiny or contact mark.
5. Are you running a shock buff?

The above tests may help isolate the problem. 
If #2 then not magazine or next round related.
If #3 may be mag spring tension issue. Try another brand mag. Wilson springs are stiff.
If #5, take it out and try it. Shok buffs increase spring tension AND reduce rearward slide travel.

Working on issue.  Thanks for suggestions.  Starting with new springs and extractor tension.  Ruled out mags and lube.  Maybe my grip is also suspect since master shooter has less of same issue when shooting my LB.

Many thanks for your suggestions.

In I found on mine that the extractor boss behind the hook was preventing proper contact with the case no matter what tension was set. Had to relieve it about .007 to get it to work properly.

+1 and make sure there in no build up in the extractor hole where that boss sits too.
