Here's a very rare and very uniquely different type of pre-transformer gun/robot figure made by a company called Bandai in 1983. It's designed to look like a S&W 469 9mm handgun. It is very cool looking in gun mode, but a little clunky-looking in robot mode.

It has three cool features to it:

1) It comes with a magazine bullet clip. You load the play bullets in the clip and then it clips into the bottom of the gun.

2) Then when you pull back the sliding bolt action at the top of the gun, it ejects the bullets like a real gun ejects the empty shell casings when fired. The bullets will not fire on thru the chamber and out thru the barrel as the robot's head blocks it and it is not hollow.

3) You can load a bullet in the end of the barrel due to it is spring-loaded. Then you can pull the trigger and it will shoot the bullet out pretty quickly.
