In a firearm, the sear is the part of the trigger mechanism that holds the hammer or striker back until the correct amount of pressure has been applied to the trigger; at which point the hammer or striker is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger. The term "sear" is sometimes incorrectly used to describe a complete trigger group. Some weapons are known for having difficult sear-disengagement, like the Browning Hi-Power, while others are prized as excellent.[citation needed]
