WARNING
Care must be exercised to either have the pistol raised or pointed downrange when loading.
Before firing, the firer must be sure that the bore of the pistol is freefrom any foreign matter. Firing a pistol with any obstruction in thebore will result in damage to the weapon and possible injury to per-sonnel.
Before starting an inspection, be sure to clear the weapon. Do not actu-ate the trigger until the weapon has been cleared. Remove magazine,inspect the chamber to insure that it is empty and check to see thatno ammunition is in position to be introduced.
Avoid skin contact with P-C-111. The compound should be washed offthoroughly with running water if it comes in contact with the skin.A good lanolin base cream, after exposure to the compound, is help-ful. The use of rubber gloves and protective equipment is recommended.
Clear the weapon of all ammunition before starting an inspection. Re-move the magazine and check the chamber to insure it is empty. DoNOT actuate the trigger until the weapon has been cleared.

Section II. OPERATION UNDER USUAL CONDITIONS
2-2. GeneralCare and cleaning of the pistol includes daily
preventive maintenance, which is the ordinarycare of the pistol required to preserve its condi-tion and appearance when no firing is done.Before-firing cleaning insures that the pistolis safe to fire and is properly lubricated for ef-ficient operation, and after-firing maintenanceinsures that all corrosion-inducing agents arecompletely removed. For cleaning proceduresrefer to paragraph 3-10a. For lubrication pro-cedures refer to paragraphs 3-8 and 3-4. Theoperator must be thoroughly familiar with allsafety features of the pistol. For safety tests,refer to table 3-2.
2-3. Loading, Firing, and Unloadinga. Loading.Warning. Care must be exercised to either
have the pistol raised or pointed down rangewhen loading.
Warning. The firer must be sure that thebore of the pistol is free from any foreign mat-ter. Firing a pistol with any Obstruction in thebore will result in damage to the weapon andpossible injury to personnel.
Draw pistol from holster, insert magazine,pull slide to the rear and release, putting around in the chamber, press the safety lock(small arms safety) up into the SAFE position.
b. Firing.To fire the pistol, press the safety lock
(small arms safety) down to the FIRE posi-tion to prevent disturbing the firing grip ofthe right hand. Obtain the correct sight aline-ment and sight picture and squeeze the trigger.To fire successive shots, the trigger must bereleased and squeezed again. When the lastcartridge from the magazine has been fired,the slide remains to the rear.
c. Unloading. To unload press the magazinecatch and remove the magazine. If the slideis in the forward position, pull the slide to therear and push the slide stop up. Inspect thechamber to insure that the pistol is clear. Pressthe slide stop down, allowing the slide to goforward. Pull trigger while weapon is in safeposition.
2-4. Firing Malfunctions and Stoppagosa. Malfunctions. A malfunction is a failure
of the weapon to function properly. Malfunc-tions are classified as defects in the weaponthat normally do not cause a break in the cycleof operation.
b. Stoppages. A stoppage is an unintentionalinterruption in the cycle of operation. A stop-page occurs when the pistol does not firethrough no fault of the firer.
c. Immediate Action in Case of Firing Mal-functions.
21
(1) Immediate action is the prompt actiontaken by the firer to reduce a stoppage. Theprocedure for applying immediate action shouldbecome instinctive to the operator of the pistol.If a stoppage occurs, immediate action is ap-plied automatically in an effort to reduce thestoppage without attempting to discover thecause at that time.
(2) In the event the slide is fully for-ward, the hammer falls, and the pistol fails tofire, apply immediate action as follows:
(a) Manually cock the hammer with-out opening the chamber and make one addi-tional attempt to fire. If the pistol still fails tofire, wait 10 seconds, and then raise the pistol.Grasp the slide with the thumb and first fingerof the non-firing hand, keeping the thumb onthe right side of the slide. Pull the slide rear-ward rapidly, to its full extent. Rotate the pis-tol to the right allowing the unfired round todrop out, release the slide and allow it to returnto the forward position, chambering a new car-tridge.
Caution. Keep the weapon pointed downrange during this operation.
(b) Aim and attempt to fire.(3) In the event the slide is not fully for-
ward, remove the trigger finger from the trig-ger guard and with the non-firing hand attemptto push the slide fully forward. If the slide willnot move forward, proceed as follows:
(a) Bring the weapon to a safe posi-tion.
(b) Remove the magazine.(c) Grasp the slide with the left hand,
pull the slide to the rear, and lock it with theslide stop.
(d) Inspect the chamber. Remove anyobstructions.
(e) Insert another loaded magazineinto the pistol
(f) Release the slide.(g) Aim and attempt to fire.
(4) If the weapon does not fire after theapplication of immediate action as outlinedabove, a detailed inspection should be made todetermine the cause of the stoppage.
Section III. OPERATION UNDER UNUSUAL CONDITIONS
2-5. General
In addition to the normal operation of the pis-tol, special care in cleaning and lubricationmust be observed where extremes of tempera-ture, humidity, and atmospheric conditions existor are anticipated. Proper cleaning, lubrication,storage, and handling of lubricants not only in-sure operation of the weapon, but also guardagainst wear of the working parts and deterio-ration of the material.
2-6. Operation in Extreme Colda. In temperatures below freezing, it is nec-
essary that the moving parts of the weapon bekept free from moisture. Excess oil on work-ing parts will solidify and cause sluggish op-eration or complete failure.
b. Before cleaning, allow the weapon to at-
tain room temperature. Perform detailed dis-assembly (par 3-9) and complete cleaning (par3-10a) before use in temperatures below OF.Working surfaces that show signs of wear maybe lubricated by rubbing lightly with a ragthat has been wet with weapons lubricating oil(LAW).
2-7. Operation in Extreme Heata. In tropical climates where temperature
and humidity are high, or where salt air ispresent, and during rainy seasons the weaponshould be disassembled, inspected, all partswiped dry, and lightly oiled daily.
b. In hot, dry climates where sand and dustmay get into the weapon, daily disassembly,inspection and cleaning should be accomplished.After cleaning, the pistol should be wiped dryand no lubricants applied.

Table 3-2. Preventive Maintenance Checks and ServicesProcedure
General appearance and proper functioning of component parts.
Warning. Before starting an inspection, be sure to clearthe weapon. Do not actuate the trigger until the weapon hasbeen cleared. Remove magazine, inspect the chamber to in-sure that it is empty and check to see that no ammunition isin position to be introduced.Safety Lock Test. With the pistol unloaded cock the hammer and
press the safety upward into the safe (locked) position. Grasp thegrip so the grip safety is depressed and squeeze the trigger tightly3 or 4 times. If the hammer falls, return pistol to organiza-tional maintenance.
Grip Safety Test. With the pistol unloaded, cock the hammer, andwithout depressing the grip safety, point the pistol downward andsqueeze the trigger 3 or 4 times. If the hammer falls because thegrip safety is depressed by its own weight return the pistol to organ-izational maintenance.
Half-Cock Position Test. With the pistol unloaded, draw back thehammer until the sear engages the half-cock position notch, thensqueeze the trigger. If the hammer falls, return the pistol to or-ganizational maintenance. Draw the hammer back nearly to fullcock position, do not squeeze trigger, and then let thumb slip offhammer. The hammer should fall only to the half-cock notch.
Diconnector Test.1. With the pistol unloaded, cock the hammer, push the slide group
1-1/4 inch to the rear and hold in that position while squeezing trigger.Let slide group go forward, maintaining pressure on trigger. If thehammer falls, return pistol to organizational maintenance.
2. Pull the slide group rearward until slide stop is engaged.Squeeze trigger and release slide group simultaneously. The hammershould not fall, if it does, return pistol to organizational maintenance.
3. Release the pressure on the trigger and then squeeze it. Thehammer should then fall, if it does not fall return pistol to organiza-tional maintenance. Also, check for a faulty disconnector which wouldprevent the hammer from falling. The disconnector should prevent therelease of the hammer unless the slide group is in a forward positionand locked into battery.
Note. This also prevents the firing of more than one shot with eachsqueeze of the trigger
