BASIC SAFETY RULES

WARNING: PLEASE READ THIS MANUAL BEFORE HANDLING YOUR FIREARM.

WARNING: FIREARMS CAN BE DANGEROUS AND CAN POTENTIALLY CAUSE SERIOUS INJURY, DAMAGE TO PROPERTY OR DEATH, IF HANDLED IMPROPERLY. THE FOLLOWING SAFETY RULES ARE AN IMPORTANT REMINDER THAT FIREARM SAFETY IS YOUR RESPONSIBILITY.

1. NEVER POINT A FIREARM AT SOMETHING THAT IS NOT SAFE TO SHOOT.

Never let the muzzle of a firearm point at any part of your body or at another person. This is especially important when loading or unloading the firearm. When you are shooting at a target, know what is behind it. Some bullets can travel over a mile. If you miss your target or if the bullet penetrates the target, it is your responsibility to ensure that the shot does not cause unintended injury or damage.

2. ALWAYS TREAT A FIREARM AS IF IT WERE LOADED.

Never assume that a firearm is unloaded. The only certain way

to ensure that a firearm has the chamber(s) empty is to open the chamber and visually and physically examine the inside to see if a round is present.

Removing or unloading the magazine will not guarantee that a firearm is unloaded or cannot fire. Shotguns and rifles can

be checked by cycling or removing all rounds and by then opening and inspecting the chamber so that a visual inspection of the chamber for any remaining rounds can be made.

3. STORE YOUR FIREARM SO THAT CHILDREN CANNOT GAIN ACCESS TO IT.

It is your responsibility to ensure that children under the age of 18 or other unauthorized persons do not gain access to your firearm. To reduce the risk of accidents involving

children, unload your firearm, lock it and store the ammunition in a separate locked location. Please note that

devices intended to prevent accidents - for example, cable locks, chamber plugs, etc, - may not prevent use or misuse of your firearm by a determined person. Firearm storage in a steel gun safe may be more appropriate to reduce the likelihood of intentional misuse of a firearm by an unauthorized child or person.

4. NEVER SHOOT AT WATER OR AT A HARD SURFACE.

Shooting at the surface of water or at a rock or other hard surface increases the chance of ricochets or fragmentation of the bullet or shot, which can result in the projectile striking an unintended or peripheral target.

5. KNOW THE SAFETY FEATURES OF THE FIREARM YOU ARE USING, BUT REMEMBER: SAFETY DEVICES ARE NOT A SUBSTITUTE FOR SAFE HANDLING PROCEDURES.

Never rely solely on a safety device to prevent an accident. It is imperative that you know and use the safety features of the particular firearm you are handling, but accidents can best be prevented by following the safe handling procedures described in these safety rules and elsewhere in the product manual. To fur ther familiarize yourself with the proper use of this or other firearms, take a Firearms Safety Course taught by an expert in firearms use and safety procedures.

6. PROPERLY MAINTAIN YOUR FIREARM.

Store and carry your firearm so that dir t or lint 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 to the barrel or accumulation of impurities which can prevent use of the gun in an emergency. Always check the bore and chamber(s) prior to loading to ensure that they are clean and free from obstructions. Firing with

an obstruction in the barrel or chamber can rupture the barrel and injure you or others nearby. In the event you hear an unusual noise when

shooting, stop firing immediately, engage the manual safety

and unload the firearm. Make sure the chamber and barrel are free from any obstruction, like a bullet blocked inside the barrel due to defective or improper ammunition.

7. USE PROPER AMMUNITION.

Only use factory-loaded, new ammunition manufactured to industry specifications: CIP (Europe and elsewhere), SAAMI

(U.S.A.). Be certain that each round you use is in the proper caliber or gauge and type for the particular firearm. The caliber or gauge of the firearm is clearly marked on the barrels of shotguns and on the slide or barrel of pistols. The use of reloaded or remanufactured ammunition can increase the likelihood of excessive cartridge pressures, case-head ruptures or other defects in the ammunition that can cause damage to your firearm and injury to yourself or others nearby.

8. ALWAYS WEAR PROTECTIVE GLASSES AND EARPLUGS WHEN SHOOTING.

The chance that gas, gunpowder or metal fragments will blow back and injure a shooter who is firing a gun is rare, but the injury that can be sustained in such circumstances can be severe, including the possible loss of eyesight. A shooter must always wear impact resistant shooting glasses when firing any firearm. Earplugs or other high-quality hearing protectors help reduce the chance of hearing damage from shooting.

9. NEVER CLIMB A TREE, FENCE OR OBSTRUCTION WITH A LOADED FIREARM.

Open and empty the chamber(s) of your firearm and engage the manual safety before climbing or descending a tree or before climbing a fence or jumping over a ditch or other obstruction. Never pull or push a loaded firearm toward yourself or another person. Always unload a firearm, visually

and physically check to see that the magazine, loading mechanism and chamber are unloaded, and action is open before handing it to another person. Never take a firearm from another person unless it is unloaded, visually and physically checked to confirm it is unloaded, and the action is open.

10. AVOID ALCOHOLIC BEVERAGES OR JUDGMENT/REFLEX IMPAIRING MEDICATION WHEN SHOOTING.

Do not drink and shoot. If you take medication that can impair motor reactions or judgment, do not handle a firearm while you are under the influence of the medication.

11. NEVER TRANSPORT A LOADED FIREARM.

Unload a firearm before putting it in a vehicle (chamber empty, magazine empty). Hunters and target shooters should load their firearm only at their destination, and only when they are ready to shoot. If you carry a firearm for selfprotection, leaving the chamber unloaded can reduce the chance of an unintentional discharge.

12. LEAD WARNING.

Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead and other substances known to cause birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands thoroughly after exposure.

WARNING: It is YOUR responsibility to know and abide by Federal, State and Local laws governing the sale, transportation and use of firearms in your area.

WARNING: This firearm has the capability of taking your life or the life of someone else! Always be extremely careful with your firearm. An accident is almost always the result of not following basic firearm safety rules.

DESCRIPTION

The new Beretta PX4 Storm Sub-Compact pistol is the most advanced expression of technological and aesthetic features in a semiautomatic sidearm. Built around a modular concept that a pistol can be adapted to different needs and modes of operation, without compromising ergonomics and the renowned Beretta reliability and performance, the PX4 Storm Sub-Compact emphasizes power, ease of handling, performance and reliability. The PX4 Storm was redesigned to minimize the overall size and weight of the pistol, while maintaining high magazine capacity, identical operating controls, significant parts interchangeability and common magazines (the full-size magazines will fit the SubCompact). Manufactured in three calibers, the PX4 Storm Sub-Compact uses a cam operated, tilt-barrel, locked breech barrel system. The light yet durable frame employs modern thermoplastic technology through the use of fiberglass reinforced technopolymer. Modular structure, ergonomics and interchangeability of parts make the PX4 Storm Sub-Compact the ideal firearm for lawenforcement use, as well as for personal defense.

SAFETY FEATURES

WARNING: Each version of the Beretta Px4 Storm Sub-Compact pistol offers different features. Carefully read the following paragraph that describes the specific characteristic of your Px4 Storm model. They provide important safety information.

NOTICE: The numbers in the figures refer to the photos on pages 11 and 12.

Px4 Storm F (Fig. 1-2): Double/single action. Ambidextrous manual safety on the slide with hammer decocking function, automatic firing pin block safety.

Px4 Storm G (Fig. 3): Double/single action. Ambidextrous manual lever on the slide with hammer decocking function with the return of the lever to the firing position, automatic firing pin block safety.

Px4 Storm D (Fig. 4): Double action only. Without manual safety-

hammer decocking. The spurless hammer, after each shot, returns to the decocked position. Automatic firing pin block safety.

Manual safety/hammer decocking lever (model F only)

(Fig. 1-2/A). The Beretta Px4 Storm pistols in F version are equipped with an ambidextrous safety lever positioned on the slide that disconnects the linkage between the trigger and the sear, allowing to decock the hammer (if cocked or if positioned on the half-cock position) with maximum safety, thanks to the rotation of the rear part of the firing pin. The safety may be engaged also with the hammer decocked and with slide open.

Hammer decocking lever on the slide (model G only) (Fig. 3). In G configuration, the lever only decocks the hammer (the hammer decocking lever, after operation, automatically returns to the firing position).

Automatic firing pin block safety (Fig. 1/B). The Beretta Px4 Storm pistols have a blocking device that prevents forward movement of the firing pin unless the trigger is completely pulled.

Slide catch (slide stop) (Fig. 1/C). The slide catch is a lever that holds the slide open and rearward after the last round is fired. This allows the user to immediately determine that the pistol does not have a round in the chamber or in the magazine.

External hammer (models F and G) (Fig. 1-2/D). The external hammer (hammer spur) allows to immediately check if the hammer is cocked, on the half-cock notch, or decocked. The hammer in D configuration is spurless.

Half-cock notch (on hammer) (models F and G) (Fig. 7). The hammer in F and G configurations has a half-cock notch that will catch on the sear, before striking the firing pin, should the hammer be released inadvertently by violently striking or dropping the pistol. In D configuration, double action only version, the hammer is spurless.

OPERATIONAL FEATURES

NOTICE: The numbers in the figures refer to the photos on pages 11 and 12.

Semiautomatic firing. Px4 Storm Beretta pistols will automatically reload after each round is fired, as long as there are cartridges in the magazine.

Barrel locking system (Fig. 2/E)

The barrel and slide are locked together as a unit at time of discharge. As they move to the rear during recoil, the barrel cam operates on the locking block to cause the barrel to disengage from the slide and allow the slide to continue its rearward travel to the final recoil position. The enlarged outer barrel muzzle diameter ensures a constant barrel to slide alignment, enhancing the accuracy of the pistol.

Single/double action (models F and G). The F and G versions fire double action on the first round (the pull on

the trigger in the double action mode will first cock the hammer completely and then release it to strike the firing pin) and single action on the following rounds (as the hammer stays in the cocked position after the first round). The first round can be fired also in single action mode if the hammer is manually cocked prior to pulling the trigger. The short and light single action trigger pull allows for faster, more accurate discharge of subsequent rounds. The long and heavy double action trigger pull is considered a safety feature because it also helps reduce the likelihood of unintentional discharge.

The hammer has three different positions:

Decocked hammer

(Fig. 5-6): The hammer is in the fully lowered position. The pull on the trigger in the double action mode will first cock the hammer completely and then release it to strike the firing pin (double action).

Hammer in the half-cocked position

(Fig. 7): By pulling the hammer rearward for a few millimeters its half-cock notch will be caught on the sear. You will feel and hear the hammer “click” into the half-cocked position. The pull on the trigger in the double action mode will first cock the hammer
