rear end of the grip frame, the barrel-receiver is properly aligned. If alignment is not achieved by hand pressure, then it is necessary to strike the muzzle of the barrel with a plastic hammer or wood mallet. Maintain pressure in a downward direction on the receiver when striking on the barrel muzzle. CAUTION: Bccause the barrel muzzle must not be damaged in any way, it is essential that any hammer applied to the muzzle be plastic or wood.
4. Grasp the mainspring housing assembly and press the bolt stop pin (which is a part of it see higure 9) upward through the holes in the receiver. As this pin is pushed upward through the grip frame and receiver it also passes through the slot in the bolt and must also pass by the rear end of the rccoil spring guide, camming the guide forward to put initial tension into the rccoil spring. The best way to accomplish this is to hold the mainspring housing as a handle in one hand and holding the gun in the other, press the pin upward until the tip of the pin protrudes beyond the top of the rcccivcr. At this point move the safety to the fire (F) position and then pull the trigger. Be certain the hammer is released to its fired position. When the hammer is in the fired position it is then possible to observe the hammer strut. That is essential to carrying out the next step.
5. Getting the mainspring housing in place correctly is best achieved in two stages: First, be certain the bolt stop pin is fully inserted, then Second, swing the housing into place and lock as described below. Remember, when the pin is protruding thru the receiver, be certain the upper end of the housing has engaged the ledge inside the lower portion of the receiver. If this engagement is not sccurc. the housing will pull out when it is swung closcd.
6. The mainspring housing is now ready to be swung shut, but it is essential that the hammer strut comes to rest on the mainspring plunger as the housing is closed.
The mainspring plunger lies inside the mainspring housing and may be seen through the slot in the upper end of the housing. If the hammer strut does not contact the mainspring plunger as the housing is swung shut, it will either be impossible to complete the closure of the housing or the housing may be closed but it will be impossible to draw the bolt all the way back. Note: It is also essential that the hammer itself be in its uncocked, upward position (resting on the firing pin) as the mainspring housing is swung shut. Some users find this phase of reassembly is best accomplished by holding the pistol with the barrel generally in a vertical position, but tilted at an angle that causes the hammer strut to drop into the correct position to 'meet' the mainspring plunger in the housing.
7. When proper engagement is achieved, closure is completed against tension of the mainspring, which can be felt as the housing is pressed home into the frame.
8. The housing latch may now be snapped shut, completing reassembly. To determine if the assembly has been correctly performed, pull bolt to its rearward position. The bolt should open fully. If it does not, disassemble and repeat step 5. above.
Note: The foregoing description of the reassembly procedure may give the impression that reassembly is difficult: but in reality it is a straightforward operation, once properly learned.
