when not in use. Take prudent safeguards to ensure your firearm does

not become available to children, untrained, inexperienced or

unauthorized people. At all times, comply with local and state laws

concerning the possession and storage of firearms.

8. USE ONLY THE PROPER AMMUNITION FOR YOUR

FIREARM.

Use only factory-loaded, new ammunition manufactured to SAAMI or

CIP specifications. Be certain that each round you use is of the proper

caliber or gauge and type for the particular firearm. The caliber of the

FN 503 is located on the rear of the barrel and is visible through the

ejection port. The use of reloaded or remanufactured ammunition

increases the likelihood of case head ruptures or other defects in the

ammunition that can cause damage to your firearm and serious injury

to yourself or others nearby.

9. PROPERLY MAINTAIN YOUR FIREARM, PRACTICE

PERIODIC MAINTENANCE AND AVOID UNAUTHORIZED

SERVICING.

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.

DO NOT, UNDER ANY CIRCUMSTANCES, ALTER THE TRIGGER,

SAFETY OR OTHER PARTS OF THE FIRING MECHANISM OF

THIS OR ANY OTHER FIREARM. FAILURE TO OBEY THIS

WARNING MAY RESULT IN INJURY OR DEATH TO YOURSELF OR

OTHERS.

Your firearm is a mechanical device and as such, is subject to wear and
