Step #1 Rotate grip frame so left side is facing downwards. Then place sear spring into frame. Orient the spring so the long leg is down and underneath the frame crosspin. The short spring leg should be oriented so it's facing upward and toward the rear of the frame. 22/45 detailed reassembly procedures

Step #2 Insert the sear pivot pin into the left hand side of the frame. Push the pin in just far enough to hold the spring in place. There should be a gap wide enough for the sear to fit into when it is put in its proper place.

Step #3 Place the sear into the frame so the top is facing rearwards. Align the sear pin holes with the pivot pin and then push the pivot pin, left, through the sear and into the other side of the frame. Leave the sear facing rearwards for the moment.

Step #4 First, install the trigger return spring and trigger return plunger. Next, rotate the sear forward. Last, swing the disconnector lever down and hook it under the right side of the sear. The disconnector lever will keep the sear in place and also prevent the trigger return plunger and spring from getting lost.

Step #5 Install the thumb safety lever through the center of the frame. Ensure the detent ball and spring are in place. Rotate the thumb safety forward until the hook just touches the sear face.

Step #6 Flip the pistol over onto its right side, install the bolt stop lever under the bolt stop pin and then align the rear portion with the hammer pivot pin hole. Insert the hammer pivot pin just enough to hold the bolt stop lever in place.

Step #7 Rotate the thumb safety forward until the hook fits over the sear face and the through hole aligns with the hammer pivot pin. Slide the hammer pivot pin in just far enough to hold the thumb safety and sear in place. Note - The pin head should be flush with the inside edge of the safety lever, leaving plenty of room for the hammer assembly when it gets installed in a few moments.

Step #7 Place the hammer assembly (Mark III magazine disconnector lever, lever spring, hammer bushing, and stepped hammer) onto the disconnector lever and swing the lever downwards into the frame. Position the long leg of the magazine disconnector lever behind the sear and place it down into the mainspring well.

Step #8 Align the hammer assembly with the frame holes and push the hammer pivot pin all the way to the right. The pivot pin should travel in far enough to sit flush on the right side of the frame.

Step #9 This is the view from the mainspring well. The long leg of the magazine disconnector lever should be positioned behind the sear and in the mainspring well.
