Regarding my TRP extractor failure, etc., in fairness to SA, here's an update
I decided it would be best to start another thread about this because as so often occurs, the original one developed some significant drift and you might not see this mixed in with all the other posts in the other thread.
Before I go on a recap of the problem. I bought (actually traded) for a SA TRP. Because of a heavy trigger I disassembled it and found some pathetic assembly and a waaaay out of spec disconnetor, which I fixed myself and would have thought no more of it other than it's inexcusible for a part like that to get into an expensive gun like that. Then, the extractor broke while I was shooting around the 200 round mark.
I decided to replace my broken extractor with a WC BP because I had it. The after the original thread, I had the thought why not get a replacement from SA and see how it does. If it breaks that would tell us something, if it doesn't that would tell us something.
So I called SA, told them about the extractor, of course there was no hesitation on their part for me to send the gun in. I just about had him talked into just sending me the extractor and remembered how sad my disconnector was. We discussed that and he was reluctant to send me a disconnector and I don't blame him at all. Here's the good news and encouraging part.
He said they would go through it with a fine tooth comb and check everything. So it should be very near a custom built gun when I get it back.
There's still no excuse for a gun leaving SA in that condition, but it did. Anyway, I whined about state of the gun and I felt it only fair to give the up side as well.
There's still more. I asked if the extractor was cast. He said yes. I asked if that has been a problem and he said no. He went on to say that any process can get a little out of spec and produce some out of spec parts on occassion, but the generally have not seen problems with their cast extractors.
Then I asked if the slide stop was also cast. He said, "Oh, no they're MIM." I said I hear those tend to break. He said, "Oh no, those work great."
