I have a G17 Gen 3 and am considering buying a G22 slide to swap out instead of purchasing a whole other pistol (G22). I know with my G23 and LWD 40-9 conversion barrel it works great but doesn't eject the brass as vigorously which I guess is due to the .40 cal extractor and ejector not getting as good a bite on the smaller 9mm casing. But if you were to just put a G22 slide on a G17 frame would the 9mm ejector work fine or cause any problems..? I will probably just buy a spare .40 cal trigger housing any way if I get a G22 slide for my G17, but just wanted to see if anyone had experience with this mix. Wanna kill these ads? We can help!
