Ive researched this issue. I have the 336 which is supposed to work in the gen 3's. Most of the time I get a good ejection but every so often one will kick out at 5 o'clock. Ill continue to put rounds through it and if it still acts up, ill see about that other ejector.
Its a darn nice gun other than that weak ejection deal. I put comp sights on it and getting where its pretty accurate for me. Plus its full FDE and dead sexy to look at :p
However, as a first time glock owner its admittedly a little frustrating considering my 8 yr old beretta px4 storm has had ZERO issues ever.
Did you happen to see my solution above?
