After hours of searching, I'm askin members if they have a link to the differences made in the late model Gen 3, G-19...I have a PLCXXX 4.0 2010.5.01... I have the older style ejector,the LCI MIM extractor, but I'm hoping for a link to the different trigger bars. are there specific problems with the late model Gen 3 19? were there 4th gen parts being used in these ? any help is appreciated.
