To reassemble the trigger on a Ward's Western Field Model 10-SB94-T, first ensure that the firearm is completely unloaded and safe to handle. Begin by inserting the trigger mechanism back into the receiver, aligning it with the hammer and sear. Secure the trigger assembly with any necessary pins or screws, making sure everything moves smoothly. Finally, perform a function check to ensure the trigger operates correctly before using the firearm.

Ensure the gun is unloaded. Remove the magazine. Pull back the operating slide and visually inspect the barrel to make sure there is not a round chambered. Loosen the screw on the band on the forward end of the stock and slide the band forward. Remove the hand guard. Remove the screw just behind the trigger guard. Remove the stock. Pull back on the operating slide spring and hold it while pulling the operating slide spring guide out of trigger housing. Carefully relieve the tension on the spring, then slide the spring guide out. Remove the trigger housing retaining screw and the two trigger housing retaining pins. Lift the receiver away from the trigger housing. Remove the operating slide by sliding it forward. Lift out the recoil plate. (Careful – it is under tension from the firing pin spring). Remove the bolt and firing pin piece and slide them apart. You have now field stripped your Iver Johnson .22 cal. carbine.

There are two things that can cause this: 1. The spring that resets the trigger is worn or is otherwise malfunctioning. 2. There is dirt or paint between the trigger and the inside of the gun, gumming it up. If you know how, take apart and clean your gun thoroughly. If not, take it to a paintball field or shop and have someone show you how.
