Thank you JCG4s, for taking the time out to do some educational post, I'll surely pass that curtesy to the next newbie along the way.
I now understand and see the ejector, and extractor, I have a few other handguns and see that you're right, the ejectors on those guns sticks out but not the GI.
I have stripped the slide and cleaned the extractor, I noticed there's no spring associated with this extractor, I guess it is tensioned by design?(or did I popped a spring and not know it??)
You said "..overtime it may become out of tune".. By that you mean wore out? rotated? loss the flexibility?
The good news is that after I typed the my last post, I cleaned it as per above and no jams!!, tried 50 rounds at the range and everything is working good. ( the bad thing is I don't know EXACTLY what cause the jams) [ofcourse the good thing is I "fixed" it and now I'm not freaking out on it]
Nevertheless, if you have the time to answer my above questions, it will be much appreciated.
and I will read your rangereport, right now, the wife and kids are waiting for their steaks on the grill....
