1. FTE = Failure to Extract or Failure to Eject.
   Failure to Extract and Failure to Eject have different meanings even though FTE is used for both terms.

   Extraction refers to the removal of the spent cartridge case from the chamber. If you have a spent case that it stuck in the chamber or your extractor is broken, you have a Failure to Extract.

   Ejection is where the spent case is forcefully thrown or ejected from the action of the gun. If the ejector is broken or the round is underpowered such that it does not have sufficient energy to drive the slide all the way to the rear you have a Failure to Eject. You can also have a Failure to Eject by “weak-wristing” or “limp-wristing” the pistol. One type of Failure To Extract is a stovepipe. A stovepipe is when the spent casing gets caught by the slide before being ejected from the gun. The empty case gets caught by the closing slide and gets stuck sticking out the side of the slide. It looks like a stove pipe. Stovepipes are associated with problems with certain ammunition or pistols that jam because the shell isn’t ejected properly.

2. FTF = Failure to Feed
