3. STORE YOUR FIREARM SO THAT CHILDREN CANNOT GAIN ACCESS TO
IT.
3. It is your responsibility to insure that children under the age of 18 or other unautho
-
rized 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. Steel gun safes 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.
4. Shooting at the surface of water or at a rock or oth-
er 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 HAN-
DLING PROCEDURES.
5.
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 ac
-
cidents can best be prevented by following the safe handling procedures de-
scribed in these safety rules and elsewhere in the product manual. To further famil
-
iarize 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.
BASIC SAFETY RULES
1. NEVER POINT A FIREARM AT SOMETHING THAT IS NOT SAFE TO SHOOT.
1. 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 be-
hind it. Some bullets can
travel over a mile. If you
miss your target or if the
bullet penetrates the tar-
get, 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.
2. Never assume that a firearm is unloaded. The on-
ly certain way to ensure that a firearm is empty
is to open the chamber and visually examine
the inside to see if a round is present.
Removing the magazine will not guarantee that
a pistol is unloaded or cannot fire. Shotguns
and rifles can be checked by cycling or removing
all rounds and by then opening the chamber so
that a visual inspection of the chamber for any re-
maining rounds can be made.

10. AVOID ALCOHOLIC BEVERAGES OR JUDG-
MENT OR REFLEX IMPAIRING MEDICATION
WHEN SHOOTING.
10. Do not drink and shoot. If you take medication that
can impair motor reactions or judgment, do not han-
dle a firearm while you are under the influence of the
medication.
11. NEVER TRANSPORT A LOADED FIREARM.
11. Unload a firearm before putting it in a vehicle.
Hunters and target shooters should load their
firearm only at their destination. If you carry a
firearm for self-protection, leaving the chamber un-
loaded can reduce the chance of accidental dis-
charge.
12. LEAD WARNING.
11. 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 ade-
quate ventilation at all times. Wash hands thoroughly after exposure.
6. PROPERLY MAINTAIN YOUR FIREARM.
6. Store and carry your firearm so that dirt or lint does not
accumulate in the working parts. Clean and oil your
firearm, following the instructions provided in this man-
ual, after each use to prevent corrosion, damage to
the barrel or accumulation of impurities which can pre-
vent use of the gun in an emergency. Always check
the barrel prior to loading to ensure that it is clean and
free from obstructions. Firing against an obstruction
can rupture the barrel and injure yourself or others
nearby. In case you hear an unusual noise when
shooting, stop firing immediately, ingage the manual
safety and unload the firearm. Make sure the chamber
is free from any obstruction or possible bullet blocked
inside the barrel due to defective or improper ammuni-
tion.
7. USE PROPER AMMUNITION.
7. 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 in-
crease the likelihood of excessive cartridge pressures, casehead ruptures or other
defects in the ammunition which can cause damage to your firearm and injury to
yourself or others nearby.
8. ALWAYS WEAR PROTECTIVE GLASSES AND EARPLUGS WHEN SHOOT-
ING.
8. 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 cir-
cumstances is severe, including the possible loss of
eyesight. A shooter must always wear impact resistant
shooting glasses when firing any firearm. Earplugs
help reduce the chance of hearing damage from
shooting.
9. NEVER CLIMB A TREE, FENCE OR OBSTRUC-
TION WITH A LOADED FIREARM.
9. Open and empty the chamber of your firearm before
climbing or descending a tree or before climbing a
fence or jumping over a ditch or obstruction. Never
pull or push a loaded firearm toward yourself or an-
other person.

The design of the fiber-glass reinforced technopolymer receiver - stock spacer and
of the stock metal plate allows one to adjust the stock drop and cast by simply modi
-
fying their assembly position. Different stock drop and cast dimensions can be ob-
tained using the extra set of spacers supplied.
STOCK DROP AND CAST SPACERS
The AL391 Urika is supplied with a modern design case and a complement of ac-
cessories: 1-round magazine capacity reducer plug, spare recoil pad, stock drop and
cast spacers, grip cap (wood stock field models only), stock swivels (field models on
-
ly), 25 ml. Beretta Gun Oil, valve hook wrenches and, for Mobilchoke
®
versions, a set
of 5 choke tubes with special spanner.
ACCESSORIES
NOTICE: The AL391 Urika barrels are not interchangeable with those of for-
mer models (AL 390, A 390 ST, A 304 etc.)
The stock is designed to accept either a plastic butt-plate or a rubber recoil pad with
-
out any adjustment. By assembling rubber recoil pads of different thicknesses, one
can modify the length of pull.
STOCK
The skilfully rounded shape of the receiver promotes instinctive and quick target ac-
quisition. The matted anti-glare black-finish of the upper and lower parts of the receiv-
er highlight the bright finish of the sides to confer to the Beretta AL391 Urika a new
appearance and distinctive character.
DESCRIPTION
STREAMLINED RECEIVER DESIGN
The unique gas operation system, with gas cylinder and self cleaning piston, is pro-
vided with a self-cleaning exhaust valve which automatically expels the excess gas of
the most powerful cartridges: The result is that the shotgun, without any adjustment ,
fires everything from the light 24 gr. (7/8 oz.) loads to the powerful 57 gr. (2 oz.) 3”
Magnum 12 ga. shotshells.
The exhaust valve assembly remains attached to the gas cylinder, thus allowing easy
and quick disassembly and reassembly of the shotgun.
GAS OPERATION SYSTEM WITH EXHAUST VALVE
The elastic recoil damper reduces stress from the impact of the breech bolt on the re-
ceiver and absorbs part of the vibrations normally transmitted to the shooter.
RECOIL DAMPER
The high strength fiber-glass reinforced technopolymer trigger plate offers many ad-
vantages: Self-cleaning property, high absorption of vibrations and more comfort to
the touch in cold weather conditions. The large opening of the trigger guard allows
the use of gloves.
TRIGGER PLATE
The cut-off control is positioned on the left side of the receiver: It can be engaged
when the breech bolt is positioned in the closed position with the use of one hand. If
the cut-off is accidentally left engaged, automatic reloading after the first shot will dis-
engage it.
CUT-OFF DEVICE
The cross-bolt safety button can be assembled for standard right-hand use or re-
versed for left-hand use.
REVERSIBLE SAFETY BUTTON
