I got my new 10mm conversion barrel from storm lake today, I have a new G21.45 3rd gen gun manufactured in the summer of 2010..... I installed the barrel, new guide rod, loaded the new 10mm mag and when I rack it back and then rack it again the round does not eject out..it kicks out just a little and with the mag out and racking it back to eject the round it just falls out the mag area. Granite I have NOT shot it yet......... When I ordered the barrel the storm lake guy told me this was a drop n go barrel...no mods needed, extractor would not need replaced or adjusted. I bought Remington 180 grain rounds with nickel plated casings...is this my problem or did storm lake not make the barrel correctly or are there other mods needed? I have read many reviews where people have just done exactly as I have and not had an issue.
