How do you remove the plug from Winchester 1400 magazine?

Answer 1

The Winchester 1400 does not have a plug, so it cannot be removed. There is only room for 2 shells, unlike the 1200/1300 pump which can hold 4 shells with the plug removed. The end of the magazine tube is where the gas piston is installed. If you look at the tube, you will see that it is crimped about half way down, separating the tube into two sections. One section acts as the magazine while the other acts as the gas cylinder (used to operate the action upon firing).

To remove the gas piston, unscrew the magazine cap, insert a screw driver into the recoil spring and hold it towards the butt of the gun. The pin connecting the carrier to the piston can then be pulled up and out. WARNING: WITH THIS PIN REMOVED, THE PISTON AND RECOIL SPRING ARE FREE TO FLY OUT OF THE MAGAZINE TUBE WITH MUCH FORCE! MAKE SURE YOU RESTRAIN THE PISTON AND SPRING PROPERLY! The piston and recoil spring are removed from the front of the magazine tube.
