Cooper's Conditions: How Ready Is Your Pistol?

When you carry a pistol, you are continuously deciding how ready it is. Loaded? Chamber empty? Hammer cocked? Safety on? Each combination has implications for how fast you can shoot, how much can go wrong by accident, and how much trust you’re putting in mechanical and human safeguards. Most shooters never think about it in those terms — they pick the carry condition their instructor taught them and stop there.

But in the 1970s and 1980s, an American shooter and writer named Jeff Cooper gave the question a vocabulary. His five-level numbered scale — Condition 0 through Condition 4 — has been the lingua franca of defensive pistolcraft ever since, and any conversation between two shooters about how they carry will sooner or later reach for those numbers.

This post walks through the conditions, what each is for, who tends to use which, and where the system came from.

Where the conditions came from

Cooper was a Marine, a writer (founding Guns & Ammo columnist), and the founder of the American Pistol Institute at Gunsite Ranch in Arizona — the school that became, in 1976, the institutional home of what Cooper called the Modern Technique of the Pistol. The Modern Technique was a synthesis: the Weaver Stance from Jack Weaver’s win at Cooper’s Leatherslap matches in the 1950s, the flash sight picture, the compressed surprise trigger break, and a doctrine of carrying a 1911 Cocked and Locked.

It was the last point — cocked and locked — that needed the most justification. To anyone who hadn’t been through Cooper’s school, carrying a pistol with the hammer all the way back looked like an accident waiting to happen. Cooper’s case was that this state, because the 1911 has both a manual thumb safety and a Grip Safety, is mechanically sound and tactically optimal. You’re never closer to a fast, accurate first shot than when the hammer is already cocked and the Trigger Press is short and clean. Once the doctrine had a name and a number — Condition 1 — it could be argued for and defended on its own terms.

The five conditions are described from Condition 4 (least ready) to Condition 0 (most ready). They were designed for the 1911 platform but apply, with some caveats discussed below, to any single-action semi-automatic.

Condition 4 — magazine out, chamber empty

Magazine out, chamber empty, hammer down, safety on or off. The pistol is essentially inert. This is the storage condition: the gun in the safe at home, the rental at the range counter before the customer takes it.

Condition 4 is not a carry condition. You can’t get to ready from here in any practical time — you have to find a magazine, insert it, rack the slide, and only then are you in a fightable state. But it is the right state for a pistol you aren’t carrying or shooting.

Condition 3 — magazine in, chamber empty

Magazine loaded, chamber empty, hammer down. To fire, the shooter must rack the slide.

This is the famous Israeli carry. The Israeli Defense Force, especially in its first two decades, was working with a mixed armament — sub-machine guns, captured weapons, multiple types of holsters, troops with widely varying training levels. Standardizing on chamber-empty carry was a hedge against the inevitable accidents that come with that kind of force-wide variation. It bought a little extra safety at the cost of a slower first shot.

In the US civilian context, Condition 3 has a few advocates and many critics. The case for: an empty chamber is one less thing that can go wrong if a holster fails or a child finds the gun. The case against: a defensive draw is already under enormous time pressure, and adding a two-handed slide rack makes one-handed engagement (you might be holding a child, opening a door, fending off an attacker) much harder. Most American defensive trainers actively discourage Condition 3 carry — but it remains common in some training cultures and is the legally-required state in some jurisdictions.

Condition 2 — round chambered, hammer down

Round in the chamber, hammer manually lowered over the chambered round.

For a 1911, getting to Condition 2 means lowering the hammer past a live primer. There is no decocker on a 1911 — the shooter must hold the hammer with the thumb while pulling the trigger, then ease it down. The procedure goes wrong every year. Cooper, and almost every modern instructor, advises against Condition 2 on a 1911. The risk-to-benefit ratio is bad: you’ve done a manipulation that can fire the gun in order to be in a state from which the next shot is a long, heavy single-action transition.

Condition 2 makes more sense on a traditional double-action (TDA) pistol like the Beretta 92 or CZ-75. Those guns are designed for hammer-down loaded chamber carry — they have a decocker that drops the hammer safely, the first shot is a long double-action pull, and follow-up shots are single-action. On those platforms, Condition 2 is the normal state. So when you hear someone say “Condition 2,” ask: what gun? The answer changes the conversation.

Condition 1 — cocked and locked

Round chambered, hammer cocked, manual thumb safety ON. This is Cocked and Locked.

Condition 1 is what Cooper advocated and what every working 1911 carrier has used ever since. The thumb safety blocks the sear and the slide. The grip safety has to be depressed to fire. The hammer is cocked, so the trigger pull is short, light, and predictable. Drawing from the holster involves wiping the safety off as the gun comes onto target — a motion practiced until it’s invisible.

Condition 1 looks alarming until you’ve handled the gun. The two safeties (thumb + grip) are the trade: more passive protection in exchange for a faster and more accurate first shot. It is, by a wide margin, the dominant 1911 carry condition.

Condition 0 — fully ready to fire

Round chambered, hammer cocked, manual safety OFF. The trigger is the only thing between the firearm and a discharge.

Condition 0 is the state your pistol is in right before you fire. As a carry condition it is generally avoided — most defensive doctrine wants the safety on between shots and during reholstering. As a moment-before-firing condition, it’s where every shot you ever take starts. The transition from Condition 1 to Condition 0 happens during the presentation, with the safety swept off at full extension. The transition back from 0 to 1 happens during reholstering — safety on first, then holster.

Treat Condition 0 the way you’d treat live current in an electrical box: it’s necessary for the work you’re doing, but you don’t leave it that way longer than you have to.

The striker-fired wrinkle

Cooper’s conditions were defined for a single-action pistol with an exposed hammer and a manual thumb safety. They map cleanly onto the 1911 and its descendants. They map imperfectly onto modern striker-fired pistols (Glock, M&P, Walther PDP, Sig P320) because:

• There is no exposed hammer to be “down” or “cocked.” The Striker is partially pre-cocked by the slide cycle and finished by the trigger press.
• Most striker-fired pistols have no manual thumb safety. The trigger itself contains the only direct user-controllable safety — the Dingus blade on a Glock, for example.

So Condition 1 and Condition 0 collapse on a stock Glock: there’s no separate safety to be on or off. Some shooters describe Glock carry as “Condition 0 forever.” Others reject the framework entirely and just say “loaded, holstered.” The 1911-era distinctions still illuminate the idea — how ready, how protected — but the explicit numbering applies cleanly only to pistols that actually have a manually-operated hammer-and-safety system.

Why people pick what they pick

The condition you carry in is mostly about what you’ve practiced and what you trust:

• Condition 1 if you carry a 1911 or other single-action pistol and have practiced the safety wipe enough that it’s part of the draw, not an extra step. The fastest first shot on a SA pistol comes from here.
• Condition 0, de facto, if you carry a striker-fired pistol with no manual safety — the gun has no other state.
• Condition 2 if you carry a TDA pistol and the platform’s first shot is supposed to be the double-action pull. (Don’t carry a 1911 in Condition 2.)
• Condition 3 if you’ve trained extensively on an Israeli carry, your jurisdiction requires it, or your risk tolerance favors the extra layer over the time penalty. Most US instructors will try to talk you out of it.
• Condition 4 for storage and for any pistol you aren’t carrying.

Underneath all of this sit the The Four Rules. The conditions are about how loaded the pistol is. The four rules are about how the loaded pistol is handled. The numbered conditions are useful shorthand and they reward thinking, but they are not a substitute for muzzle awareness and trigger discipline. Two safety rules must fail simultaneously for an accident to occur. The conditions don’t change that arithmetic — they just tell you, at any given moment, which failures the gun is currently capable of.

Practical takeaway

Pick a carry condition that fits your platform, train it the way you’d train any other manipulation, and keep it consistent. The worst condition is the one that varies — sometimes hot, sometimes cold, sometimes safety on, sometimes off — because that’s the condition where surprise becomes the deciding factor.

Cooper’s gift was naming the variables. The numbers don’t tell you what to do. They tell you what to talk about.
