These weapons also generally lack any type of external safety. DAO is common among police agencies and for small, personal protection firearms. The primary drawback is that the additional trigger pull weight and travel required for each shot reduces accuracy. Pre-set triggers offer a balance of pull weight, trigger travel, safety, and consistency.
However, if a user shooting under stress short-strokes the trigger by only releasing it halfway, the trigger will reset, but with a 38 N (8.5 lb f) pull. This temporary increased trigger pull is intended to prevent negligent discharges. Double-action – firearms trigger: Pressing the trigger 1) cocks, and 2) drops the hammer. The hammer can ...
Examples of the variety of typical semi-auto mechanisms are a stiff double-action trigger pull with the safety off (Beretta 92F/FS), a double-action with no external safety (SIG Sauer P-series, or Kel-Tec P-32), or a crisp single-action trigger pull with a manual safety engaged (M1911, FN Five-seven and certain configurations of the HK USP).
Trigger: A mechanism that actuates the firing sequence of a firearm. Triggers almost universally consist of levers or buttons actuated by the index finger. Trigger pull restrictor (TPR): A quasi-selector device intended for automatic firearms using a staged trigger. Trunnion: a cylindrical protrusion used as a mounting and/or pivoting point. On ...
A binary trigger (or pull and release trigger) is a type of device that allows a semi-automatic firearm to fire at an increased rate. A binary trigger works by firing one shot upon pulling the trigger and then firing a subsequent shot upon release of the trigger. Binary triggers are installed through modification of the fire-control group.
The takeup is the least critical stage of the trigger pull, and individual preferences vary widely. Two-stage triggers, for example, consist of a noticeable takeup, followed by a distinct increase in the force required to pull the trigger, followed by the break. A single-stage trigger, on the other hand, has no discernible movement before the ...
V0: CDA/DA trigger system. The CDA aka LEM trigger is a dual-stage trigger that always fires from a hammer down DA mode, but has an internal mechanism that is cocked with each cycle of the action. It provides a cocked double-action trigger pull of 20 N (4.5 lb f) (+4/-2 N) and an uncocked double-action trigger pull of 51 N (11.5 lb f) (±5 N).
Same as V1, but it uses a medium Trigger Return Spring. The medium Trigger Return Spring (TRS) strikes a compromise for a cleaner trigger reset like the V2 version while providing a trigger pull weight in between V1 and V2. V4.1/CH CDA aka LEM 27.5 N (6.2 lb f) 10 mm (0.39 in)
