FTE- can be failure to extract and/or failure to eject. either way you have a jam, but w/ slightly different mechanical causes.
FTF- can be failure to feed (the next round from the mag that is) and/or failure to fire (also sometimes called "click no bang" the loudest noise on the range).
WECSOG- Wiley E. Coyote School Of Gunsmithing. Always have a spare part handy when attempting to replicate what "somebody did to their ..." espicialy in the way of homemade add-ons. Even something like polishing syou have to be careful with. Luckily steyrs are very modular designs (a cornerstone of their philosophy that applys to their rifles and pistols).
JUST BECAUSE HE DID IT DOESN"T MEAN I CAN.
One exapmple... I can break my steyr down to all the subassemblys, but will not trust myself w/ bending in feedlips of a .40 mag to feed 9mm and hold more rounds, others can but I'm afraid I'll whack it to hard
Limpwristing- Just simply not holding tight enough. You want to lock up your wrists, see the excellent pictorial in our "tactics and Training" forums. Lightweight poly pistols are espicialy prone to this as they don't have the weight at the front end, and our tight tolerance steyrs more so. THE #1 CAUSE OF O.O.B.
IPSC- International Practical Shooting Confederation sport developed in the 60's in California to involve "scenario" stages involving skills such as, moving while firing, engaging multiple targets, firing from behind cover, etc. All while being timed and usualy from the draw.
USPSA- the US body of IPSC
IDPA- International Defensive Pistol Association, off shoot of IPSC by members that felt ipsc had become too "gamey" w/ special built guns "race guns" and uber expensive equipment as well as strategies to shave time that would be quite tacticly unsound in a real world gunfight. Rules changes involved things like no dumping mags on the ground that still had rounds (might need them in a real gun fight so put the mag in a pocket), and keeping behind cover when possible. There is some current grumbling about equipment resrictions and round limitations and holster requirements (it is supposed to be "real world" gear and to make different pistols as equal as possible).
3-GUN- Same "practical" type matches but w/ the use of rifles, shotguns, and pistols. Various governing bodies (including IPSC, but not IDPA).
edit:
Eye Dominance- just like you have a dominant/strong hand and off/weak hand so do your eyes. To test Hold out your finger and focus on it , now close one eye and then the other. It will jump. The side that it is the same place compared to the background is your dominant eye. If your strong hand is not on the same side as your dominant eye you'll have hella problems w/ sight picture. There's many ideas on how to compensate.
