Abstract: A kit includes a deterrent device, a grip activation system, and a housing supporting the grip activation system. The housing positions the grip activation system so that a sensing space of the grip activation system extends at least partly adjacent to a trigger guard of the deterrent device. The grip activation system includes an emitter configured to emit first electromagnetic radiation having a first wavelength; a detector configured to detect second electromagnetic radiation having the first wavelength; and a controller.

A housing latch biasing member biases the housing latch into the second latch position.

Abstract: Airguns are provided. In one aspect, a shuttle having a breech bushing therein is moved between a cocking position where a projectile is loaded into a breach bushing channel and a firing position where the breech bushing channel is located between a port from which compressed air flows firing and a barrel opening into which the compressed air advances the projectile. The barrel has a barrel guide surface at the back barrel face, wherein the breech bushing has a shaped surface facing the barrel and wherein the breech bushing shaped surface and the barrel guide surface are configured to interact as the barrel is moved from the cocked position to the firing position to urge the breach insert to move within the shuttle passageway in a manner that reduces the extent of any misalignment between the breech bushing channel and the opening.
