Further, and I am not saying that
@Cropduster172 did this, I see a lot of guys at the gun range abuse their guns without knowing that they are abusing them.
E.g. putting a single round in the chamber, and slamming the slide home after wards. Total extractor abuse. You load the gun from the magazine, so that the round slides
under the extractor hook. Slamming the slide forward with a round already in the chamber forces the extractor to jump the cartridge rim, a task for which it was not designed. On something like a 1911, that can cause extractor problems.
Not the fault of the gun, but the fault of the operator.
A Glock is more tolerant of this abuse, but it remains an abusive practice no matter what platform. On a 1911, you’re going to need a new extractor if that’s your habit, and the extractor tension will need to be checked when that new extractor is installed. On a Glock, it’s an easy spring install to restore proper function.
