This glossary is a list of definitions of terms and concepts used in the rules and discussions with respect to 1Gun.
| Term | Definition |
|---|---|
| 180-degree rule | Is defined as the imaginary plane that moves with the shooter and remains parallel to the back berm. This plane defines both the horizontal and vertical area the muzzle is allowed to point. |
| Accidental discharges (AD) | Any of the following discharges:
|
| Aftermarket | Items not manufactured by, or available directly from, the original firearm manufacturer. |
| Appearing target | A target which is not visible until activated or revealed. |
| Array | A grouping of more than one target. |
| Barrier | A wall or other range prop which helps define a course of fire. Unless defined by the COF, this is considered Hard Cover. |
| Behind | Uprange of and within the lateral confines of the specified object; e.g. "standing behind the table" means uprange of the table and inside the lines defined by the edges of the table. |
| Berm | A raised structure used to contain bullets and/or to separate one shooting bay from another. |
| Bullet | The projectile in a round intended to strike a target. |
| Caliber | The diameter of a bullet measured in millimeters (or thousandths of an inch). |
| Cold Range | All firearms will be unloaded unless instructed to do so by the SO at the start of a course of fire. Firearms may only be handled in designated SAFE AREAS. Absolutely NO ammunition or dummy rounds may be handled in safe area. |
| Chief Safety Officer (CSO) | The primary authority over all persons and activities in the stages under his/her control. See Safety Officer. |
| Course of Fire (COF) | (Also “course”) An expression used interchangeably with “Stage”. |
| Course Type |
Short Course - Must not require more than 12 rounds to complete. Course design and construction must not require more than 6 scoring hits from any single location or view. Medium Course - Must not require more than 24 rounds to complete. Course design and construction must not require more than 6 scoring hits from any single location or view. The course must also require at least 2 locations or views. Long Course - Must not require more than 36 rounds to complete. Course design and construction must not require more than 6 scoring hits from any single location or view. The course must also require at least 3 locations or views. |
| Disappearing target | A target which when activated and after completing its movement exposes less than 3x5 inches of scoring area. |
| Draw | The point at which a handgun is removed or disengaged from the holster so as to allow access to any portion of the interior of the trigger guard. |
| Dropped gun | A condition in which a competitor loses control of their firearm (i.e. the firearm is no longer in control by either hand of the competitor). |
| Engaging | (As in “engaging a target”) A competitor is actively aiming at and firing at least one shot at a target that is within view and not through any hard cover. |
| Exclusion Zones | Scoring Exclusion Zones can be denoted by black areas on the target. Hits in these areas do not count regardless if it is on threat or non-threat targets. Please note, these are only exclusion zones for the given target. So, if the bullet passes through an exclusion zone in target-1 and then strikes target-2 in a non-painted area, target-2 hit will be scored regardless if it is a threat or a non-threat. |
| Facing downrange | Not facing uprange. |
| Facing uprange | Face and feet pointing directly (180 degrees) away from the midpoint of the back berm (i.e. shoulders and hips square to the back berm). |
| Fault line | A physical ground reference line in a course of fire which defines the limit(s) of the shooting area. |
| Foot Fault | Is defined when at least one foot is touching any object (ground, prop, etc.) that is outside the shooting area when the shot is broke. |
| Freestyle | Competitors may engage the targets with one or both hands. |
| Handling | (As in “handling a firearm”) The act of manipulating, holding, or gripping a firearm while the trigger is functionally accessible. |
| Hard Cover | Hard cover are used to represent impenetrable objects in real life. These should not be shot and if they are, the bullet is considered "out of play" at that point and can not be used in the scoring from that point on for both threats and non-threat targets. Hard cover comes in two basic flavors:
|
| Kneeling | A body position wherein at least one knee is in contact with the ground or stage surface. |
| Loaded firearm | A firearm having a live round, empty case or dummy round in the chamber or cylinder or having a live or dummy round in a magazine inserted in the firearm. |
| Loading / Reloading |
The insertion of ammunition into a firearm. Loading begins when the magazine or cylinder release has been pressed or the loading device has been removed from the holder, regardless if the magazine has fallen or the cylinder is fully open. Loading is declared completed, when the ammunition is inserted, firearm is in battery (slide forward or cylinder closed and ready to fire), and in the case of a reload, the magazine/loading device removed from the firearm is no longer in the competitor’s hand. |
| Match Official | A person who has an official duty or function at a match. |
| Match Director (MD) |
The primary authority over all persons and activities for the entire match to ensure the match is fun, fair, and consistent for all participants based on the 1Gun rules. All match disqualifications and appeals to arbitration must be brought to the match director attention. |
| Movement | Taking more than one step (both feet have moved) in any direction, or changing body position (e.g. from standing to kneeling, from seated to standing etc.). |
| Must | This means the same as “will,” “shall,” etc. Compliance is mandatory. |
| No-shoot(s) / Non-Threat(s) | Target(s) that incur penalties when hit. |
| Not applicable | The rule or requirement does not apply to the particular discipline, Division, or match level. |
| Occurrence | For the purposes of assessing penalties, e.g. contact with any object outside the shooting area, an occurrence is defined as shooting at an array of targets from a single location / view in the course of fire. If the shooter moves to another view / location and continues to contact an object outside the shooting area, that constitutes a second occurrence. |
| PCC | Pistol Caliber Carbine |
| Power Factor (PF) | Equals bullet weight in grains multiplied by velocity in feet per second (as measured by a chronograph) divided by 1000. |
| Premature start | Beginning an attempt at a COF prior to the “start signal”. |
| Prone | The competitor is laying on the ground, or other designated surface, with the front of the chest closest to the ground. |
| Radial tears | Tears in a cardboard target radiating outwards from the diameter of a bullet hole. |
| Reshoot | A competitor’s subsequent attempt at a course of fire, authorized in advance by a Safety Officer and/or Match Director. Mandatory for stage malfunctions and optional for shooter's equipment malfunctions (but will incur the Reshoot-Penalty). |
| Safety Officer (SO) | The match official that issues range commands, oversees competitor compliance with the written stage briefing and closely monitors safe competitor action. |
| Scoring Styles | There are two types of scoring styles in 1Gun:
|
| Scoring Area | The total area of a target that if a bullet impacts the target, the hole will be scored. This does not include exclusion areas of the target. Scoring areas less than a 5"x5" can not exceed 20 yards for freestyle, 15 yards for strong hand only, and 10 yards for weak hand only. |
