THE BASIC RULES OF SAFE FIREARMS HANDLING
We believe that Americans have a right to purchase and use firearms for lawful
purposes. The private ownership of firearms in America is traditional, but that
ownership imposes the responsibility on the gun owner to use his firearms in a way
which will ensure his own safety and that of others. When firearms are used in a safe
and responsible manner, they are a great source of pleasure and satisfaction, and
represent a fundamental part of our personal liberty.
Firearms do not cause accidents! Firearms accidents are almost always found to have
been the result of carelessness, or ignorance on the part of the shooter of the basic
rules of safe gun handling.
The following rules must be observed by gun users at all times. Safe gun handling is
not just desirable, it is absolutely essential to your safety, the safety of others, and the
continuation of gun ownership and sport shooting as we know it today.
1. LEARN THE MECHANICAL AND HANDLING
CHARACTERISTICS OF THE FIREARM YOU ARE USING.
Not all firearms are the same. The method of carrying and handling firearms
varies in accordance with the
mechanical provisions for avoiding
accidental discharge and the various
proper procedures for loading and
unloading. No person should handle
any firearm without first having
thoroughly familiarized himself with
the particular type of firearm he is
using, and with safe gun handling in
general.
2. ALWAYS KEEP THE
MUZZLE POINTED IN A
SAFE DIRECTION.
Be sure of the bullet stop behind your
target, even when dry-firing. Never let
the muzzle of a firearm point at any
part of your body or at another person.
This is particularly important when
loading or unloading a firearm. In the
event of an accidental discharge, no
injury can occur as long as the muzzle
is pointing in a safe direction. A safe
direction means a direction which will
not permit a discharged bullet to strike
a person, or to strike an object from
which the bullet may ricochet.

INSTRUCTION MANUAL  READ THE INSTRUCTIONS
  AND WARNINGS IN THIS
  MANUAL CAREFULLY BEFORE
  USING THIS FIREARM.

							44
A safe direction must take into account the fact that a bullet may
penetrate a wall, ceiling, floor, window, etc., and strike a person or
damage property. Make it a habit to know exactly where the muzzle of
your gun is pointing whenever you handle it, and be sure that you are
always in control of the direction in which the muzzle is pointing, even
if you fall or stumble. Keep your finger off the trigger until you are ready
to shoot.
3. FIREARMS SHOULD BE UNLOADED WHEN NOT IN
USE
.
Firearms should be loaded only
when you are in the field or on the
target range or shooting area,
ready to shoot. Firearms and
ammunition should be securely
locked in racks or cabinets when
not in use. Ammunition should
safely be stored separate from
firearms. Store your firearms out
of sight of visitors and children. It
is the gun owner’s responsibility
to be certain that children and
persons unfamiliar with firearms
cannot gain access to firearms, 
ammunition, or components.
4. BE SURE THE BARREL IS CLEAR OF OBSTRUCTIONS
BEFORE SHOOTING.
Even a bit of mud, snow or excess
lubricating oil or grease in the
bore or an improperly seated bullet
may cause the barrel to bulge, or
even burst on firing, and can cause
serious injury to the shooter and
bystanders. Be sure that you are
using projectiles of the proper
caliber for the gun you are using.
If the report or recoil on firing
seems weak, or doesn’t seem quite
right,  CEASE FIRING
IMMEDIATELY, and check to be
sure that no obstruction has
become lodged in the barrel. Never
try to shoot out an obstruction!

5. BE SURE OF YOUR
TARGET BEFORE YOU
SHOOT.
Don’t shoot unless you know
exactly where your bullet is going
to strike. Be sure of the bullet
stop behind your target, even
when dry-firing with an unloaded
gun. If you are in the field
hunting, do not fire at a
movement or noise. Take the time
to be absolutely certain of your
target before you pull the trigger.
6. WEAR SHOOTING
GLASSES AND HEARING
PROTECTORS WHEN
YOU SHOOT.
All shooters should wear
protective shooting glasses and
adequate hearing protectors when
shooting. Exposure to shooting
noise can damage hearing, and
adequate eye protection when
shooting is essential. Bits of
metal percussion cap and hot
powder gasses are ejected in
many directions when firing any
percussion muzzleloader.
7. NEVER CLIMB A TREE
OR FENCE WITH A
LOADED FIREARM.
Put the firearm down carefully
before climbing a fence, and
remove the cap or unload it before
climbing or descending a tree or
jumping over a ditch or other
obstruction. Never pull or push a
loaded firearm toward yourself or
another person. When in doubt, or
whenever you are about to do
anything awkward, remove the cap
or unload your gun!  
						

							46
8. DON’T SHOOT AT A
HARD SURFACE, OR AT
WATER.
Bullets can glance off many
surfaces like rocks or the surface
of water and travel in
unpredictable directions with
considerable velocity.
9. NEVER TRANSPORT A
LOADED FIREARM.
Firearms should always be
unloaded before being placed in a
vehicle. A suitable carrying case
or scabbard should be used to
carry an unloaded firearm to and
from the shooting area. With
muzzleloaders, it’s much easier
and safer to fire them into a safe
backstop before bringing them
into car, camp, or home.
10. AVOID ALCOHOLIC
BEVERAGES WHEN
SHOOTING.
Don’t drink until the day’s
shooting is over. Handling
firearms while under the
influence of alcohol in any form,
or medications that could affect
your judgment or co-ordination,
constitutes a criminal disregard
for the safety of others. 
						

							A BRIEF ACCOUNT OF AN EXTRAORDINARY
ACHIEVEMENT: RUGER FIREARMS
One of the few American firearms manufacturers whose management
has remained unchanged since starting in business, Sturm, Ruger &
Company, Inc., had its beginning in a small machine shop occupying a
rented frame building in Southport, Connecticut. In January, 1949, with
an initial investment of only $50,000 and an idea, William B. Ruger and
Alexander M. Sturm started production of a .22 caliber autoloading
pistol–a design which was so successful that it became the cornerstone
upon which one of the most comprehensive lines of sporting firearms
ever made in America was established. After Alex Sturm’s death in 1951,
William B. Ruger continued to direct the company alone and today, as
Chairman of the Board, he is actively involved in the creative
engineering of new products and continues to provide the leadership
which has made this 49-year-old company a sound and successful
enterprise.
Sturm, Ruger & Company, in this relatively short time, has established
itself as a leading small arms design organization, developing a unique
and broad line of fine quality sporting, military and police firearms to
become one of the world’s most famous producers of revolvers, pistols,
rifles and shotguns. From 1949 thru 1998 Ruger craftsmen have built
many millions of firearms.
During its four decades of growth and progress under the leadership of
William B. Ruger, the company has developed a business philosophy and
implemented policies which represent a constructive influence in the life
of modern America. From the beginning, Sturm, Ruger & Company
played a positive role in conservation efforts and has supported the
interests of the National Rifle Association, National Shooting Sports
Foundation, and many regional sportsmen’s organizations. The company
has always endeavored to market its firearms for constructive and
recreational purposes, to emphasize the traditional aspects of shooting,
to render meaningful public services and to encourage shooters in
constructive and responsible participation in the shooting sports.
Today, Sturm, Ruger & Company is particularly mindful of those
elements which have contributed to the creation of its success, and
extends heartfelt thanks to its many loyal employees and customers.

							WHY NO WARRANTY CARD HAS BEEN
PACKED WITH THIS NEW RUGER FIREARM
The Magnuson-Moss Act (Public Law 93-637) does not require any
seller or manufacturer of a consumer product to give a written
warranty. It does provide that if a written warranty is given, it must be
designated as “limited” or as “full” and sets minimum standards for a
“full” warranty. Sturm, Ruger & Company, Inc. has elected not to
provide any written warranty, either “limited” or “full”, rather than to
attempt to comply with the provisions of the Magnuson-Moss Act and
the regulations issued thereunder. There are certain implied
warranties under state law with respect to sales of consumer goods. As
the extent and interpretation of these implied warranties varies from
state to state, you should refer to your state statutes. Sturm, Ruger &
Company wishes to assure its customers of its continued interest in
providing service to owners of Ruger firearms.
