    Is anyone having ejection for BTF issues while using a Lonewolf, or other manufacturer, 9mm to .40 conversion barrel in their Gen 4 Glock 23's?

    It seems to me that if you were to put in a conversion barrel than you would have the same problem with the Gen 4 19's are having.
  2. I think you mean .40 to 9mm conversion...I have one but not for the Gen4 issues in mine with 124GR ammunition...mostly Speer Gold Dot and Speer Lawman...I had tried some cheap Aguila in 115GR and had 2 in 100 FTRB that just a touch to the slide cured...but that was enough for me not to buy any more for my G23 wanna be G19...

    I have had zero issues but I went ahead and bought a gen 4 G19 RSA for use in my 23 when I had in the 40-9 conversion barrel.

    0 BTF

    0 BTF

    Gen3 G32 barrel- 200 rounds of WWB 125gr and 100 rounds Underwood 125gr Gold Dot.
