Career
In 1976 Cooper founded the ''American Pistol Institute'' (API) in Paulden, Arizona
Paulden is a census designated place (CDP) in Yavapai County, Arizona, Yavapai County, Arizona, United States. The population was 5,231 at the 2010 United States Census, 2010 census.

(later the Gunsite Academy). Cooper began teaching shotgun and rifle classes to both law enforcement and military personnel, as well as civilians, and conducted on-site training for individuals and groups from around the world. He sold the firm in 1992 but continued living on the Paulden ranch. He was known for his advocacy of large-caliber handguns, especially the Colt 1911 and the .45 ACP cartridge.[
Cooper, along with Michael Dixon and Thomas Dornaus, worked on the design of the ]Bren Ten

A pistol is a type of handgun, characterised by a gun barrel, barrel with an integral chamber (firearms), chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the Englis ...
for personal protection. The modern technique emphasizes two-handed shooting using the Weaver stance, competing with and eventually supplanting the once-prevalent one-handed shooting style. The five elements of the modern technique are:
*A large caliber pistol, preferably a semi-automatic
*The Weaver stance
*The draw stroke
*The flash sight picture
*The compressed surprise trigger break[Morrison, G. and Cooper, J., "The Modern Technique of the Pistol", Paulden: Gunsite Press, 1991.]
Firearm conditions of readiness
There are several conditions of readiness in which such a weapon can be carried. Cooper promulgated most of the following terms:
*Clear and Safe: Slide locked to the rear, chamber empty, no magazine in the gun.
*Condition 4: Chamber empty, no magazine in the gun, hammer down.
*Condition 3: Chamber empty, full magazine in place, hammer down.
*Condition 2: A round chambered, full magazine in place, hammer down.
*Condition 1: A round chambered, full magazine in place, hammer cocked, safety on. Also referred to as "cocked and locked."
*Condition 0: A round chambered, full magazine in place, hammer cocked, safety off.
Condition 0 is considered "ready to fire"; as a result, there is a risk of accidental or negligent discharge carrying in Condition 0.
Combat mindset and the Cooper color code
The most important means of surviving a lethal confrontation, according to Cooper, is neither the weapon nor the martial skills. The primary tool is the combat mindset, set forth in his book, ''Principles of Personal Defense''.[Cooper, Jeff, ''Principles of Personal Defense'', Paladin Press, ]
Cooper came up with a color code, consisting of four colors including white, yellow, orange, and red:
The color code, as originally introduced by Cooper, had nothing to do with tactical situations or alertness levels, but rather with one's state of mind. Cooper did not claim to have invented anything in particular with the color code, but he was apparently the first to use it as an indication of mental state.
The USMC uses "Condition Black," although it was not originally part of Cooper's color code. According to Massad Ayoob, "Condition Black," in Cooper's youth, meant "combat in progress." "Condition Black" is also used to mean "immobilized by panic" or "overwhelmed by fear".
Rifle concepts
Cooper is best known for his work in pistol training, but he favored the rifle for tactical shooting. He often described the handgun as a convenient-to-carry stopgap weapon, allowing someone the opportunity to get to a rifle:
Scout rifle

, a forward-mounted optical sight (long eye relief scope), and fitted with a practical sling. Cooper defined his goal: a general-purpose rifle is a conveniently portable, individually operated firearm, capable of striking a single decisive blow on a live target of up to 200 kilos in weight at any distance at which the operator can shoot with the precision necessary to place a shot in a vital area of the target. Cooper felt the scout rifle should be suited to a man operating like the scout Burnham, either alone or in a two- or three-man team.
In late 1997, with Cooper's oversight, Steyr Mannlicher produced a rifle to his "scout" specifications. Cooper considered the Steyr Scout "perfect." Riflemen regard Cooper's development of the scout rifle concept and his subsequent work on the evolution of the Steyr-Mannlicher Scout rifle as his most significant and enduring contributions to riflecraft.

Ammunition concepts
Cooper was dissatisfied with the small-diameter 5.56×45mm NATO ( .223 Remington) of the AR-15 and envisioned a need for a large-bore (.44 caliber or greater) cartridge in a semi-automatic rifle

Along the lines of the Thumper concept, Tim LeGendre of LeMag Firearms developed .45 Professional, the predecessor of the .450 Bushmaster cartridge, and later built and delivered an AR-15 in .45 Professional to Cooper.
Writing
In 1997, Cooper wrote that he coined the term hoplophobia in 1962 "in response to a perceived need for a word to describe a mental aberration consisting of an unreasoning terror of gadgetry, specifically, weapons."
In addition to his books on firearms and self-defense, Cooper wrote several books recounting his life adventures plus essays and short stories, including ''Fire Works'' (1980); ''Another Country: Personal Adventures of the Twentieth Century'' (1992); ''To Ride, Shoot Straight and Speak the Truth'' (1988); and ''C Stories'' (2004). His daughter Lindy Wisdom published a biography, ''Jeff Cooper: the Soul and the Spirit'' (1996).

Personal life
