1. FOREWORD ALWAYS KEEP THIS MANUAL WITH YOUR FIREARM. INCLUDE IT WITH THE PISTOL WHEN IT CHANGES OWNERSHIP OR WHEN IT IS LOANED OR PRESENTED TO ANOTHER PERSON.
IT IS YOUR RESPONSIBILITY TO KNOW AND ABIDE BY FEDERAL, STATE AND LOCAL LAWS GOVERNING THE SALE, TRANSPORTATION, OWNERSHIP, POSSESSION, AND USE OF FIREARMS IN YOUR AREA. CALIFORNIA STATE WARNING, SAFETY AND WARRANTY NOTES According to state law, California requires that firearms manufacturers, distributors and retailers include conspicuous, specific warnings with firearms sold in that state.
2. BASIC SAFETY RULES READ THIS MANUAL BEFORE HANDLING YOUR FIREARM. WARNING: FIREARMS CAN BE DANGEROUS AND CAN CAUSE SERIOUS INJURY, DAMAGE TO PROPERTY OR DEATH, IF HANDLED IMPROPERLY. THE FOLLOWING SAFETY RULES ARE IMPORTANT REMINDERS THAT AS A FIREARMS OWNER SAFETY IS YOUR RESPONSIBILITY. THERE IS NO EXCUSE FOR CARELESS OR ABUSIVE HANDLING OF ANY FIREARM. HANDLE THIS FIREARM AND ALL OTHER FIREARMS WITH RESPECT FOR THEIR POWER AND POTENTIAL DANGER AT ALL TIMES. 1.
not fire even if the “safety” is in the on “safe” position. Mechanical “safeties” merely aid safe gun handling and are no excuse for pointing your firearm’s muzzle in an unsafe direction. Some firearms do not have a mechanical safety. Many target firearms, lever-action firearms and pistols do not have manual “safety” mechanisms. Therefore, it is critical to read and understand the owner’s or operator’s manual for every firearm that you use, which explains the safe operation of the firearm.
fragmentation of the bullet which can result in the bullet striking an unintended target. 6. WHENEVER YOU HANDLE ANY FIREARM, OR HAND IT TO SOMEONE, ALWAYS OPEN THE ACTION IMMEDIATELY AND VISUALLY CHECK THE FIREARM’S CHAMBER AND MAGAZINE TO MAKE CERTAIN THAT THE FIREARM IS COMPLETELY UNLOADED. Completely unload your firearm as described in Section 6. Make certain the firearm does not inadvertently contain any ammunition. Remember, merely removing the magazine does not mean the chamber is unloaded.
Store and carry your firearm so debris does not accumulate in the working parts. Clean and oil your firearm following the instructions provided in this manual after each use to prevent corrosion damage or accumulation of debris. Make sure that no obstructions remain in the barrel. Firing the pistol with an obstruction in the barrel can cause extensive damage to your firearm and serious injury to yourself and others.
Always wear appropriate eye protection when disassembling and cleaning your pistol to prevent the possibility of springs, springtensioned parts, solvents or other agents from contacting your eyes. 11. AVOID DROPPING FIREARMS OR SHOOTING FROM UNSTABLE POSITIONS. Shooting from unstable positions is dangerous. Doing so increases the risk of falling or dropping the firearms. The following rules should always be observed.
instructions in section 11.1 and inspect the barrel for obstructions before shooting. Never inspect the barrel while the firearm is loaded or prior to complete field stripping. Mud, snow and an infinite variety of other objects may inadvertently lodge in a barrel bore. If an obstruction is seen, no matter how small it may be, clean the bore with a cleaning rod and patch as described in section 12.1 of this manual.
Closely supervise newcomers to the shooting sports. Encourage enrollment in firearm and shooting safety courses. 17. NEVER DRINK ALCOHOLIC BEVERAGES OR TAKE JUDGEMENT/REFLEX IMPAIRING MEDICATION OR DRUGS BEFORE OR DURING SHOOTING. Your vision, motor skills and judgment could be dangerously impaired, making your gun handling unsafe to you and to others. 18. READ AND HEED ALL WARNINGS IN THIS OWNER’S MANUAL, ON AMMUNITION BOXES AND WITH ALL ACCESSORIES THAT YOU INSTALL ON YOUR FIREARM.
Never fire the pistol upon purchase without first inspecting cleaning and lubricating it before use. Pay special attention that all foreign material is removed from the bore of the barrel to prevent an unsafe condition. 3.
CAREFULLY INSPECT EACH CARTRIDGE BEFORE IT IS LOADED IN THE MAGAZINE. BE CERTAIN THE CARTRIDGE CASE IS NOT SPLIT OR DEFORMED AND THAT THE CARTRIDGES DO NOT POSSESS ANY OTHER DENTS OR DEFECTS. For best results, use new factory manufactured ammunition from a reputable manufacturer. Primers, powder, cartridge cases and bullets can deteriorate with time and cause damage to the firearm or injury to the shooter or others.
If you have concerns about the compatibility of a particular ammunition type with your FN pistol, contact FN customer service before using any such ammunition. 4. DRY FIRING & “DUMMY” ROUNDS Dry firing is defined as firing a firearm with no ammunition in the chamber. Occasional dry firing of your FN 509 and for disassembly is acceptable. Regularly dry firing your FN 509 pistol for practice or training may result in damage to the striker.

When the safety levers are moved down the red dot indicating that the pistol will fire is exposed and the firing mechanism is free to operate. The safety lever is retained in the selected position by a detent and will snap into location when engaged or disengaged.
9.3 AMBIDEXTROUS SLIDE STOP FIGURE 31 The FN 509 slide stop is fully ambidextrous meaning that the control levers are located on both sides of the frame within easy reach of the thumb of the shooting hand and protected from unintentional activation by a guard located in front of and below the slide stop lever. The Slide stop lever. slide stop is automatically engaged when the last shot from a magazine is fired or the slide is retracted with an empty magazine in the pistol.
9.5 LOADED CHAMBER INDICATOR FIGURE 33 The loaded chamber indicator is located on the right side of the slide just behind the ejection port. When a cartridge is present in the chamber, the extractor is deflected by the case exposing a red dot on the slide directly above the slide stop and providing a tactile indication that the Loaded chamber indicator. chamber is loaded when a finger is placed on the wide groove at the front of the rear slide serrations on the right side of the pistol (Figure 33).
NOTE: Some jurisdictions limit the magazine capacity. All FN pistols intended for sale in those jurisdictions will be shipped with magazines not exceeding the specified number of rounds in compliance with local or state law. Verify the capacity of your magazine before loading it in your pistol to avoid violating local laws in these FIGURE 34 jurisdictions. 9.
Note: The FN 509 has been tested to ensure safe operation. The reliability of the pistol may be affected by the installation of a suppressor or muzzle device. FIGURE 36 9.9 INTERCHANGEABLE BACKSTRAPS The FN 509 has been designed to use interchangeable backstraps that allow the pistol to be adapted to fit your hand better (Figure 36). Backstraps provided vary by model. Interchangeable backstraps. 9.
The sights of the FN 509 should be aligned with the top of the front sight even with the top of the rear sight and an equal gap between the rear sight and the sides of the front sight. The point of impact will be at the top of the front sight when the sights are properly aligned. The dots provided on the sights are intended as an aid in low light conditions and provide a less precise but faster sight alignment. If installing and using an optical sight, the optic must be zeroed for accurate targeting.
