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. AMMUNITION
AMMUNITION NOTICE: FN specifically disclaims responsibility for any
damage or injury occurring with, or as a result of, the use of faulty, non-
standard, remanufactured, hand-loaded or reloaded ammunition, or
cartridges other than those for which the firearm was originally chambered.
Serious damage, injury or death could result from the use of incorrect
ammunition, from firing against a bore obstruction or from propellant
overloads. Use of improper ammunition, such as listed previously will void
the manufacturer’s warranty. Use only commercially manufactured
ammunition made in accordance with SAAMI (Sporting Arms and
Ammunition Manufacturers’ Institute) or CIP (Commission internationale
permanente pour l’épreuve des armes à feu portatives “Permanent
International Commission for the Proof of Small Arms”) standards. Be
certain that the ammunition is the appropriate caliber and loading for the
firearm and is clean, dry and in good condition. The caliber of your FN pistol
is marked on the portion of the barrel visible through the ejection port.
THE FN 509 IS DESIGNED TO SAFELY AND RELIABLY
FUNCTION WITH +P AMMUNITION. THE AMMUNITION SOLD

GUIDELINES AND MAY DEVELOP CHAMBER PRESSURE IN
EXCESS OF INDUSTRY STANDARDS. DO NOT USE +P+

SPECIFICALLY INTENDED FOR USE IN SUBMACHINE GUNS
AS CHAMBER PRESSURE MAY REACH OR EXCEED THE
