    Hey all, I had the same problem most of you do with my L9-A1, even after 500 rounds of a variety of bullet weights. True, it likes the hotter stuff but I bought it for plinking. Thus, I made a steel guide rod and used a variable 14 lb 1911 spring (NOT the plunger spring which I tried first and absolutely does NOT work). Sure as the pope defecates in the woods, it started to consistently eject brass in the 3-4 o'clock direction. The factory spring is too heavy for typical yankee loads and thus the flacid ejection pattern. I suspect this is due to 9mm chamber c.i.p pressure testing standards being 10,000 psi higher than SAAMI (implying that, on average, they rock hotter ammo across the pond). All I had were the variable type but you should be able to tune it to your loads with something in the 14lb weight range.
    All the best

    Thank you for the info.
    I have a m9a1 and maybe I can find a 1911 variable spring lying around that I can use. I did install the upgraded extractor kit also and it is much much better so now I guess I just like the idea of trying to get the awesome m9a1 to function a little bit better.
