I was able to remove the firing pin spring when I liberally hosed down the firing pin channel with spray CLP product I use, I depressed the firing pin plunger and the spring came out. I then used an AR-15 pipe cleaner I had on hand and with CLP, cleaned out the firing pin channel thoroughly.
But I still could not remove the extractor, even if I depress the firing pin plunger, the extractor would not come out. My SA GI Champion does not have this firing pin plunger, so its extractor comes out easily.
So I researched further, online, and read that the rear sight has to be removed to allow for the firing pin plunger and spring to be removed from the top of the slide and then and only then will the extractor come out.
The Para Ord manual for the GI Expert says nothing about removal of the firing pin or extractor.
My gentle hammering on the extractor, using material between the punch and the extractor, caused slight hammer marks on the front/rear of the extractor; I was depressing the firing pin plunger while hammering. So now I may have caused very slight marring to the extractor claw and the rear of the extractor by the firing pin stop, so I ordered a new extractor from Brownells, $25.00 U.S., and I'm going to have my local gunsmith install it for me.
I called Para Ord in North Carolina to confirm what I read about the extractor and the firing pin plunger, they would not confirm what I read due to liability issues. They suggested I might mail the entire firearm to them and have them install the new extractor, for about $80 incl. labor. I refused as I've shipped a 1911 before and it took weeks to get it back. I don't want to wait weeks to get my 1911 back.
Everyone has asked me why would I want to remove the extractor and like I said previously, that Tula ammo powder gunked everything up and I'm sure the extractor itself got gunked... sure I cleaned the extractor claw, but the rest of it is yet uncleaned.
I learn by doing, that's why I hauled off and tried to strip down my Para Ord on my own.
I want to learn this stuff inside and out and just reading about it doesn't work for me and just leaving well enough alone is not in my DNA; I don't want to have faith that if I left the filthy gunked up extractor alone it would continue to function properly ... helluva thought if I had to use the Para to defend myself only to find out I had a FTE in a gunfight because the extractor malfunctioned because I didn't clean out that gunk from the Tula ammo.
The old SEAL saying is "if you even think there might be a problem, you have a problem, so go fix it so you won't have a problem."
I want all my firearms 100% operational, otherwise why have them at all?
