This article/section contains unofficial information, concepts, or terminology derived from or based on community discussion, invention, or knowledge. It may be subjective and contain information or terminology that is not used by Digital Extremes or in official WARFRAME communications, and may not be an officially recognized concept.
Some informal labels are used to refer to specific sub-category of triggers.
Trigger Type refers to the firing mechanism within primary and secondary weapons. The fire button (default LMB ) has varying effects depending on the equipped weapon.
List of Trigger Types
- For a list of all weapons with a particular trigger type, see Weapon Comparison.
- Auto, also known as Automatic or Full-Auto, shoots a continuous stream of bullets while the fire button is held down.
- Auto-Spool is a type of automatic fire that gradually builds up fire rate the longer the fire button is held down.
- Semi, also known as Semi-Automatic or Semi-Auto, fires a single bullet per press of the fire button.
- Burst is a type of semi-automatic fire that shoots two or more bullets, often in a burst-like fashion, per press of the fire button.
- Auto-Burst is a combination of automatic and burst firing types that shoots two or more rounds while the fire button is held down. Currently exclusive to the
Cyngas, 
Battacor, and 
Morgha. - Simultaneous Burst (informal label) is a Burst subtype in which the burst is fired in a span of 0 seconds i.e. simultaneously – in a manner which is similar to innate Multishot – the only practical difference being that ammo is spent for each projectile fired; exemplified by
Quartakk and 
Kuva Quartakk. - Mag Burst (informal label) is a Burst subtype in which the entire magazine is shot out during the burst like
Pandero's alt-fire.
- Auto-Burst is a combination of automatic and burst firing types that shoots two or more rounds while the fire button is held down. Currently exclusive to the
- Duplex shoots one round when pressing the fire button, and shoots another round when releasing the fire button. Exclusive to the
Tigris, 
Sancti Tigris, 
Tigris Prime, 
Zylok and 
Zylok Prime. - Active is found in deployable grenade launchers (e.g.
Penta) and landmines (e.g. 
Talons) causes the fired shot to linger for a few seconds. The active shot can be manually detonated using the Alternate Fire button (default MMB ). - Held is a type of automatic fire that shoots a continuous beam, exclusive to Continuous Weapons. Unlike automatics that fire bullets, these beam weapons often consume ammo at a halved rate and multishot generates extra instances of damage, but possesses limited range.
- Charge builds up power in a weapon while the fire button is held down, and shoots when the fire button is released. A circular bar appears on the reticle to indicate charging. Some chargeable weapons require a full charge to fire, while others fire automatically at a full charge.
- There are several charging types:

| Full Quickshot | Indefinite Hold |  Drakgoon ( Kuva),  Dread,  Miter,  Paris ( MK1,  Prime),  Cernos ( Rakta,  Prime,  Mutalist),  Artemis Bow,  Ballistica ( Rakta,  Prime),  Epitaph,  Stug Alt-Fire,  Balefire Charger,  Velocitus,  Corvas
