Embodiments of the present disclosure include methods, apparatuses, and systems for receiving feedback during transport. Embodiments include a transportation system comprising a tractor, a trailer, and a sensor feedback system. Sensor feedback system may include a tilt sensor system mounted on at least one of the tractor, a dolly, a first trailer, and a second trailer, and a user feedback system mounted within the tractor. Tilt sensor system may measure tilt of at least one of the dolly, first and second trailers, and first and second containers attached to the first and second trailers, to obtain tilt information, and send tilt information to the user feedback system via a communication system. User feedback system may receive the tilt information and alert a driver of the tractor if the tilt information is above a predetermined level.

A training magazine has a body configured to be removably received in the magazine well, a motor connected to the body and operable to generate a motive force, an energy storage element operably connected to the motor and configured to store potential energy generated by the motive force, and an actuator operably engaged to the energy storage element and to the reciprocating action element, and operable to transmit the potential energy to reciprocate the action element. The reciprocating element may be a pistol slide. The energy storage element may be a spring. The spring may be a torsion coil spring having a cylindrical shape with opposed circular ends. There may be an input rotor operably connected to the motor and to a first end of the spring. There may be an output rotor connected to an output end of the spring and to the actuator.

An auto-loading firearm having a live fire mode, in which the firearm operates to discharge, and a training mode in which the firearm does not discharge. In the training mode, the firearm provides for resetting the trigger after simulated firing of the firearm.

A gun includes a receiver assembly, a magazine, a trigger assembly, a sear assembly, a blowback assembly and a reciprocating slide. When the trigger rotates, the first connecting member is capable of pulling the trigger slide to move linearly, and driving the second connecting member, the sear assembly and the force-storing slide to move linearly towards the same direction. Moreover, the force-storing slide compresses the blowback spring, and the blowback slide receives a restoring force of the blowback spring to drive the reciprocating slide to move backward. The gun could achieve a simulation effect of rotating actions of the trigger, as well as a simulation effect of blowback actions of the reciprocating slide.

A firearm training barrel for a replica gun, the gun having a slide and a magazine with a follower. The barrel includes an extended or extendable member positioned or positionable to simulate the presence of one or more pellets in the magazine, whereby the replica gun can be fired even after the magazine's follower has reached the top of the magazine.
