A trigger of a crossbow includes a trigger guard including an inner periphery. A trigger is pivotably located within the trigger guard. The trigger includes a space defined in the rear face thereof. A switch member includes a body portion, and an operation section and a contact section are respectively formed on two ends of the body portion. The body portion is pivotably connected in the space. A resilient member is biased between the contact section and the inner end of the space. The contact section is pushed by the resilient member to contact the inner periphery of the trigger guard to restrict the trigger from being pulled. When the operation section is pulled, the switch member is pivoted and the contact section compresses the resilient member. The contact section is moved away from the inner periphery of the trigger guard such that the trigger is able to be pulled.

A firearm attachment is disclosed including a first side wall, a second side wall, and a bottom wall extending between the first side wall and the second side wall. The bottom wall spaces the first side wall from the second side wall to define a space therebetween for receiving a trigger guard of a firearm. The firearm attachment further includes a first attachment protrusion extending from the first side wall toward the second side wall for engaging the trigger guard of the firearm and a second attachment protrusion extending from the second side wall toward the first side wall for engaging the trigger guard of the firearm.

A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.

The present disclosure relates to a firearm which may include a frame with a first outer wall, and a second outer wall opposite the first outer wall. A laser module may be disposed between the first and second outer walls. An alignment pin may be in communication with the first outer wall and may be configured to move the laser module relative to the frame.

Various examples of a detachable trigger guard for firearms are described. The trigger guard as a monolithic piece has components including a main body, a first connection portion at a first distal end of the main body, and a second connection portion at a second distal end of the main body opposite the first distal end thereof. At least one of the first connection portion and the second connection portion of the detachable trigger guard is elastically deformable to allow the detachable trigger guard to be removably coupled to a receiver portion of the firearm below a trigger of the firearm with the first connection portion coupled to either or both of a first pair of through holes on the receiver portion of the firearm and with the second connection portion coupled to either or both of a second pair of through holes on the receiver portion of the firearm.

An unfinished firearm frame having a top adapted to receive a slide. Where rear restriction protrusions extend from the top of the frame near a rear of the frame which restricts addition of the slide to the frame and front restriction protrusions extend from the top of the frame and forward of the at least one rear restriction protrusion which restricts addition of the slide to the frame. Where there is a recoil assembly block adapted to prevent a recoil assembly from being assembled into the frame. A jig having a right side and a left side to receive and clamp the frame. The jig including three pin hole guides, a removal guide edge for each of the at least one rear restriction protrusion and the at least one front restriction protrusion and a recoil assembly cutout to allow a tool to pass to the recoil assembly block.
