How can you assess the effectiveness of the extractor based on this week's lecture material?

• A. Focus solely on the geometry of the recoil spring, as it is the most critical factor in extraction and ejection.
• B. Prioritize the recoiling speed of the bolt/slide.
• C. Inspect the ejector face for angles that propel the cartridge at a downward 45-degree angle.
• D. Check for a significant gap between the extractor and the cartridge rim when the cartridge head is flush against the slide/bolt face.

Answer: (D)

Extractor effectiveness comes down to whether the claw reliably grips the rim of a cartridge when it’s fully seated in the chamber. If, with the cartridge head pressed flush against the slide/bolt face, you can see a noticeable gap between the extractor and the cartridge rim, that means the extractor isn’t contacting or holding the rim properly. That gap flags inadequate extractor tension or wear, which can lead to failure to extract or eject reliably. In practice, you want the rim to be held firmly by the extractor so the hook can pull the case out as the slide moves rearward. The other options don’t test the rim engagement directly: recoil-spring geometry doesn’t reveal extractor grip, bolt/slide speed affects cycling but not the extractor’s grip on the rim, and ejector-face angles deal with ejecting the spent case, not extracting it from the chamber.
