Okay, some might consider this a petty beef, but I'm almost ready to scream.
FTF sometimes = failure to fire.
FTF sometimes = failure to feed.
FTE sometimes = failure to extract.
FTE sometimes = failure to eject.
All of these *different* "jams" take place at different stages of the firing/empty removal/reloading sequence. Some can be magazine-related, others are almost impossible to be mag-related. Any may be ammo-related, but whether it's a "gun" problem is often debatable.
May I suggest for future TFL Semiauto Forum posts:
FTFr = failure to fire.
FTFd = failure to feed.
FTEx = failure to extract.
FTEj = failure to eject.
Are there any other ambiguities I've missed?
FWIW, I'm always skeptical of dismissing FTFr as "ammo problem" that doesn't count for assessing reliability of the firearm WHEN THE ROUND FIRES ON THE SECOND TRY. Inadequate hammer spring/striker spring power or excess friction in the firing mechanism can cause this--and such causes CAN BE/ARE design, materials, or durability defects in the firearm!
Rant mode off.
