![]() those who have a ' hair-trigger' laugh reaction). Shall make those laugh whose lungs are tickled o'th' sear" (i.e. The term may be related to the French verb serrer, "to grip", and the noun serre, "claw, talon, grasp." The term appears in Hamlet: "the Clown Manufacturer: Sears SKU: 1967SearsSpringSummerCatalogPDF 12. The sear has been found on early weapons such as the crossbow. It can be measured, regulated and adjusted, but it is a complicated mechanical problem. Trigger pull is related to the interaction of the sear with the trigger and the spring. However, because of the spring tension placed on the disconnector by the firing pin block, the weight of the trigger pull is significantly increased. On other handguns, such as the Series 80 version of the M1911, a firing pin block acts as an internal safety, which is disengaged by the disconnector after the trigger is pulled. When the trigger is still under pressure by the firearm operator, the disconnector will not retract to its resting position. Many firearms, such as the M1911 pistol, use a notch in the slide of the handgun that the top end of the disconnector returns to after the trigger is released. The sear on many firearms is often connected to a disconnector, which, after a cycle of semi-automatic fire has proceeded, keeps the hammer in place until the trigger is released and the sear takes over. When a gunsmith does a "trigger job" to improve the quality and release of a trigger pull, most often the work includes modifying the sear, such as polishing, lapping, etc. Aftermarket trigger companies, such as Bold, Timney, and Jewell, produce products in which sear contact is adjustable for personal preference. Larger sears create creep while shorter ones produce a crisp pull. Trigger sears are a key component for trigger pull characteristics. In this case, the selector switch disengages one over the other. On many select-fire weapons, two sears exist, one for semi-automatic fire and the second for full-automatic fire. A Browning BLR rifle contains three sears, all used simultaneously for hammer release. A Ruger Redhawk double/single-action revolver contains two, one for single-action release and the other for double-action release. For example, a Ruger Blackhawk single-action revolver contains one for releasing the hammer. Within a trigger group, any number of sears may exist. CAMBRIDGE, MA-(Marketwire - Jun 2, 2011) - Ah, spring: its time to finally whip yourself into shape for summer - no more excuses. The sear spring is accessable under the right grip panel.The sear spring has a large affect on the trigger weight and the pistols accuracy. The term "sear" is sometimes incorrectly used to describe a complete trigger group. When the trigger is pulled, the sear moves out of its notch, releasing the hammer and firing the gun. Sear: A sharp bar, resting in a notch (or in British: "bent") in a hammer (or in British: "tumbler"), holding the hammer back under the tension of the mainspring.
