The parts that I identified as castings are: hammer, sear, disconnector, extractor. I suspect that most new guns on the market have some of those parts cast. I used SVI for the trigger group parts, and a Cylinder & Slide extractor.
It's supposed to be spring steel. On most new 1911s it isn't, it's just a casting with a slight amount of natural spring to it. Now you know why so many people have FTF/FTE problems with their new 1911s! Replacing the extractor with a new unit like a Wilson or Ed Brown is the first order of business.Originally posted by BB:
How can the extractor be cast? Its a spring.
Wilsons and Browns are tool steel, if I recall correctly the only true spring steel extractor on the market right now is made by Cylider & Slide. Another way to go is with the Aftec, which is independently sprung. I'm not sure I totally distrust cast parts(aside from the extractor that is), it all depends on the quality of the casting.Originally posted by dsk:
