It's funny --- I've had a couple of 1911s for awhile (a Colt and a SA), both Series 70-type (no extra doodads inside). Then I got a Colt Defender, which is a Series 90 --- in other words, a firing pin block, plunger, spring, bar, ... blahblah ...
).
The more complex model is actually
easier to strip the slide parts. Push the FP in, press the block plunger in, the FP
stays forward, pop the FP stop out, point the back end of the slide against a piece of cardboard on the table, press the plunger in, ker-pop, the FP blips out, shake out the plunger and spring, pull the extractor. Which sounds ridiculously complex when you say it or read it, but beats the heck out of pushing the FP in and juggling the block out, without getting skewered
or playing find-the-part
. Reassembly is even easier, since that little plunger obligingly holds the FP in while you put the block back in.
There was a point. Honest!
Which is: NOTHING beats doing it the first time. Drawings, diagrams, videos, manuals --- once your eyes, hands, and head wrap around it one or two times, it's yours forever. All the stuff that put little beads of sweat on your forehead become little jokes.
Now --- slightly off-topic --- once you've wandered through your 1911s, pull the guts out of a Ruger MkIII and do the trigger, using the manual diagrams! Get to
know what sweat is!
