LOL, I don't know why people want to call the extractor a PT-1911 problem. The extractor is and has always been a 1911 problem. And make no mistake, the PT-1911 is an excellent example of a 1911.
So if you haven't heard this before (search is your friend), here it is one more time.....1911 extractors are like light bulbs. They can break early or they may last thousands of rounds. It does not matter if they are made by elves out of unobtainium, as long as they adhere to the original John Browning design, they will be like light bulbs. You can "tune" them, buff and polish them, but they are still light bulbs. So really, rather than spend a bunch of money on a "magic" one, buy 2 cheap ones so you have a backup.
And don't forget Rule #1 of the 1911: There are no drop in parts for the 1911, even the grips. Oh you may find a part that drops in without needing to be fit, but I guarantee that was by accident and not design. There are just too many variances between 1911s, even within the same make and model. An extractor is not hard to fit, if you feel you can do the job. But the part does need to be fit. The one thing about a 1911 is that a good 1911 smith can make a great 1911 out of cheap parts, but a 1911 just assembled out of the best parts on earth will rarely even function. How good a 1911 can be is determined by how well the 1911 smith knows his trade. The better the 1911 smith the better the 1911.
One last thing before I get off the soap box, dropping a round in the barrel and releasing the slide on it is a guaranteed way to break an extractor pretty quick.
