FIREARMS SAFETY - YOUR RESPONSIBILITY
SAFETY MUST BE THE FIRST AND CONSTANT CONSIDERATION OF
EVERY PERSON WHO HANDLES FIREARMS AND AMMUNITION.
This Instruction Manual is designed to assist you in learning how to use and care for your
RUGER
®
SR-SERIES pistol properly. Please contact us if you have any questions.
Only when you are certain you fully understand the Manual and can properly carry out its
instructions should you practice loading, unloading, etc. with live ammunition. If you
have any doubts about your ability to handle or use a particular type of gun safely, you
should seek supervised instruction. Such personalized instruction is often available from
gun dealers, gun clubs or police departments. If none of these sources can help you,
contact the National Rifle Association, 11250 Waples Mill Road, Fairfax, VA 22030-7400.
They will assist you.
The person possessing a gun has a full-time job. You cannot guess; you cannot forget. You
must know how to use your firearm safely. Do not use any firearm without having a
complete understanding of its particular characteristics and safe use. Remember: There is
no such thing as a foolproof gun.
