Good question. I don't know, I use extractor. I can speculate though.
Everyone on this forum has some degree of interest in S&W firearms which varies greatly from casual to passionate. Those on the casual level communicate well enough to be understood. Those on the passionate level find satisfaction in researching, knowing and using S&W authentic language. That also has an added benefit of passing on the knowledge/passion to those who want to know as much as they can. And every level in between those two extremes.
So there's no one-size-fits-all and members are free to participate at any level they like.
