Combat Arms 2869 Grove Way Castro Valley, California 94546-6709 Telephone (415) 538-6544 Accurizing the Beretta 92-F/M-9 The tune up procedures for this weapon consist of the use of simple stoning and smoothing in the trigger area, hammer, hammer strut and sear. No other adjustment should be made. The result of this work will be a much smoother trigger pull in double and single action. These procedures assume that you are a competent armorer or gunsmith and they must not be attempted by unqualified persons. No liability, either express or implied, is given for the use of these procedures. INITIAL DISASSEMBLY OF THE WEAPON CAUTION: MAKE SURE THE MAGAZINE IS REMOVED FROM THE BERETTA 92-F AND THE PISTOL IS EMPTY BEFORE ATTEMPTING ANY OF THE FOLLOWING PROCEDURES. 1. Complete the initial field stripping to remove the slide and barrel assembly from the frame. 2. To prevent loss of the disassembly button and spring, be sure to release the button pressure slowly after the removal of the disassembly latch lever. To remove the disassembly latch lever, push in on the disassembly latch button on the right side of the frame and, while holding the button in, rotate the disassembly latch lever on the left side of the frame upward until the disassembly latch lever cannot be further rotated and is in contact with the slide rail. While still maintaining firm pressure on the disassembly latch button, pull out and rotate upward the disassembly latch lever in order to remove it from the frame. Slowly release the pressure on the disassembly latch button and remove the disassembly latch button and disassembly latch button spring from the right side of the frame. When removing the left and right pistol grip stocks, the lock washers may either remain seated or come loose. Use care not to lose the lock washers. Remove the grip screws. Using the forefinger of one hand, insert the finger into the bottom of the magazine well and gently push up on the inside of the pistol grip stock. Repeat the procedure to remove the other stock. 3. Place the Beretta 92-F on its left side and locate the trigger bar spring just below the trigger bar. Use a pair of needle nose pliers to carefully unseat the upper portion of the trigger bar spring from the trigger bar. Gently lift up and remove the trigger bar spring from the hole in the receiver. Next, remove the trigger bar by unseating it from the frame. This is accomplished by inserting the forefinger into the receiver and pushing outward on the trigger bar. Then pull the trigger bar out from the right side of the weapon's frame. a. The rear left side portion of the trigger bar contains the trigger bar lug. The trigger bar lug should be smoothed with either a piece of crocus cloth or hard Arkansas stone. The object is to polish, not to remove metal. b. On the forward left side of the trigger bar is the cross pin (called the trigger bar post) that goes into the right side of the frame through the trigger bar post hold and into the trigger. Use crocus cloth to remove all burrs from the trigger bar post and ascertain that it is as smooth as possible. 4. Next, remove the slide stop. The slide stop is located on the left side of the Beretta 92-F. Rotate the slide stop slightly upward and pull out until the slide stop can rotate freely downward. Then remove the slide stop and slide stop spring. a. The cross pin of the slide stop passes through the trigger and should be smoothed with crocus cloth to prevent trigger drag. 5. The lanyard loop spring pin is removed next. During the removal of the lanyard loop spring pin, be sure the drift punch described below is left in place to prevent accidental loss of parts or injury to yourself or others nearby. With a 1/8 inch drift punch, drive out the lanyard loop spring pin from the left side of the frame towards the right side. Be sure to leave the punch in place when the pin is removed. Place the lanyard loop on a soft support and push down firmly on the top of the receiver to overcome the main spring tension. While maintaining downward pressure, slowly remove the punch and then slowly release the pressure to permit the lanyard loop and main spring to be removed. Using a punch, remove the headed hammer pin by pushing it out from the left to the right. Lift up and remove the hammer from the frame. Finally, rotate the frame upside down and allow the hammer strut to fall free of the frame. a. Now that this portion of the disassembly is completed, take the hammer strut and, using a hard Arkansas stone, remove all burrs and smooth with crocus cloth. b. Using crocus cloth, remove any burrs on the main spring. c. Examine the hammer notches and stone smooth using a hard Arkansas stone. 6. The final step involves removal of the sear itself. During the removal of the sear pin, use your finger to maintain control of the sear spring to prevent ejection of the spring and/or loss of it. With a 3/32" punch, push the sear pin out of the sear pin hole from the right side to the left side. Rotate the frame upside down over your work surface. With the top of the frame resting against the work surface, withdraw the punch to allow the sear and sear spring to fall free and clear. a. Using a hard Arkansas stone or crocus cloth, smooth the sides of the sear. Clean up the sear's mating surfaces with the hard Arkansas stone. Lastly, using the hard Arkansas stone, chamfer the leading edge of the sear ever so slightly. 7. All work is completed. Clean the weapon with Break-Free CLP(tm) and reassemble it. Test fire the weapon before delivering it to the client.
