OVERVIEW
PINCH POINTS CAUTION KEEP FINGERS CLEAR OF COCKING MECHANISM AND PINCH POINTS NOTED IN ILLUSTRATION 9.
OPERATION OF MANUAL SAFETY CAUTION: Keep safety “ON” unless actually firing. Always move the safety to its intended position and check it. The safety is not “ON” unless it is fully in the “ON” position. Never depend on a safety mechanism or any other mechanical device to justify careless handling or permit the rifle to be pointed in an unsafe direction. Never point the air rifle at anything you do not intend to shoot.
• Slide the safety switch rearward to fully cover the “F” and/or red dot. This will expose the “S” in front of the slide indicating that the air rifle is “ON SAFE”. • When ready to fire, make sure air rifle is pointed in a safe direction before sliding the safety switch forward to cover the “S” and expose the “F” and/ or red dot. This indicates that the air rifle is in the “OFF SAFE” or “FIRE” position. 11.
COCKING AND LOADING WARNING NEVER PLACE YOUR HANDS OR FINGERS OVER OR IN FRONT OF THE MUZZLE. NEVER ALLOW THE MUZZLE TO POINT TOWARD YOURSELF OR ANYONE ELSE DURING COCKING. ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION. DO NOT TOUCH THE TRIGGER OR MOVE THE SAFETY TO THE “OFF SAFE” POSITION DURING COCKING OR LOADING. DO NOT COCK YOUR AIR RIFLE UNTIL YOU ARE READY TO LOAD AND FIRE. CAUTION DO NOT FIRE YOUR AIR RIFLE WITHOUT A PELLET IN THE CHAMBER. THIS WILL CAUSE DAMAGE TO THE RIFLE.
WARNING DO NOT RELEASE THE BARREL UNTIL THE TENSION HAS BEEN CAPTURED BY THE MECHANISM. RELEASING THE BARREL BEFORE IT HAS BEEN FULLY COCKED WILL CAUSE THE BARREL TO SUDDENLY SNAP CLOSED, WILL DAMAGE THE RIFLE AND MAY CAUSE SERIOUS INJURY OR DEATH. CAUTION DO NOT PULL THE TRIGGER WITH THE BARREL IN THE OPEN POSITION. THIS COULD CAUSE THE BARREL TO SNAP CLOSED, MAY DAMAGE THE RIFLE, AND MAY RESULT IN INJURY OR DEATH. 13.
COCKING AND LOADING COCKING: Before cocking the air rifle, move the safety to the “ON SAFE” position. Make sure that the muzzle is pointed in a safe direction. With one hand, grasp the stock firmly, without touching trigger, and brace the butt end of the stock against your upper thigh. With the other hand, tap the top side of the suppressor to release the detent and break open the breach. With that same hand, grasp the suppressor close to the end without placing your hand in front of the muzzle.
.
COCKING AND LOADING LOADING: Always be certain you are using the correct size (caliber) pellet for your air rifle. Refer to the markings on your air rifle to confirm the correct pellet size. Never reuse ammunition. • Insert a pellet, head first, into the breech end of the barrel which is exposed when you cock the air rifle. Make sure that you seat the pellet fully, ensuring that the pellet skirt is flush with or below the face of the breech. Avoid causing any damage to the pellet skirt.
• Once the pellet is loaded properly, close the barrel by grabbing the suppressor and rotating it firmly back up to the original closed and locked position. The air rifle is now ready to fire. Keep the safety “ON SAFE” and the rifle pointed in a safe direction until you are ready to fire. 17.
AIMING AT A SAFE TARGET Always aim your air rifle in a SAFE DIRECTION. Always choose your target carefully. Always be sure of your backstop. Always be sure that the entire path of your pellet, even beyond the target, is safe. Never shoot at glass, hard surfaces or water. The pellet may bounce off or ricochet and hit someone or something you had not intended to hit. CAUTION INSPECT YOUR BACKSTOP FOR WEAR BEFORE AND AFTER EVERY USE. DISCONTINUE USE IF THE BACKSTOP SURFACE SHOWS SIGNS OF FAILURE.
FIRING FIRING THE AIR RIFLE: When you are sure of your target and backstop, and the area surrounding the target is clear, take the air rifle “OFF SAFE” and fire when ready. AIMING – SCOPE: Check the owner’s manual included with your scope for directions to properly mount and operate the scope. 19.
MATCHLITE™ TRIGGER ADJUSTMENT NOTE: This feature is added for advanced shooters. Most shooters can use the factory settings and should not need to make adjustments. If you are not experienced in adjusting two-stage triggers, leave the trigger as set by the factory, or seek assistance from SIG Sauer Customer Service. WARNING INCORRECT ADJUSTMENTS AND MODIFICATIONS CAN MAKE THE GUN UNSAFE TO USE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS INJURY OR DEATH.
This air rifle is equipped with a two-stage adjustable trigger. The trigger can be adjusted for pull weight and transition point to the second stage. Remember that small adjustments can make a noticeable change to the feel of the trigger. It is recommended to make small changes and test the trigger with each incremental adjustment. Before making any adjustments to the trigger, make sure the air rifle is “ON SAFE”, pointed in a safe direction, unloaded and not cocked.
MATCHLITE™ TRIGGER ADJUSTMENT 1. To shorten the length of the second stage, turn the screw clockwise (inward). 2. To increase the length of the second stage, turn the screw counter-clockwise (outward).
TRIGGER WEIGHT ADJUSTMENT: The factory setting for the trigger weight is 3 lbs. The trigger weight can be adjusted in 2 oz increments from a minimum of 2.5 lbs to a maximum of 3.5 lbs. The trigger weight adjustments are made by turning the embedded screw behind the receiver using either the included tool, or a #1 Philips screwdriver. 1. To decrease the trigger pull weight by 2 oz, insert the included tool or a screwdriver into the hole.
TROUBLESHOOTING 1. UNLOADING A PELLET: The safest way to unload a pellet is to fire the air rifle at a SAFE TARGET. WARNING IF A PELLET DOES NOT LEAVE THE BARREL AFTER PULLING THE TRIGGER AND FIRING, IT MAY BE JAMMED. THIS CAN BE DANGEROUS. PUT THE AIR RIFLE “ON SAFE” AND KEEP IT POINTED IN A SAFE DIRECTION. WARNING DO NOT RELOAD THE AIR RIFLE IF A PELLET IS JAMMED. DO NOT COCK THE AIR RIFLE DURING THE REMOVAL OF A JAMMED PELLET. NEVER LOOK DOWN THE MUZZLE END OF THE BARREL.
2. REMOVING A JAMMED PELLET: If a pellet does not leave the barrel after pulling the trigger and firing, it may be jammed. Follow these steps to clear the barrel. a. Point the air rifle in a SAFE DIRECTION b. Hold the air rifle close to your body with the butt end on your upper thigh. c. With the palm of your free hand tap the muzzle end of the barrel to expose the breech. d. Keeping a tight hold of the rifle look down the barrel through the breech end to confirm that there is a pellet lodged in the barrel.
TROUBLESHOOTING NOTE: DO NOT fire your air rifle without a pellet in the chamber (dry fire). This may permanently damage your air rifle. If you are not able to unjam your air rifle by following these instructions, take no further action. Call SIG Sauer customer service at 603.610.3000, option 1 for further instructions.

SPECIAL NOTES TO FIREARMS SHOOTERS The ASP20 produces a “whiplash” type of recoil that is typical of all break barrel air rifles. This can make the rifle hold sensitive. For best accuracy: •Be consistent in where and how you hold the air rifle. Allow the air rifle to recoil the same way each time. •Avoid resting the air rifle directly on rigid surfaces such as a rocks, sandbags or fence posts.
SPECIAL NOTES TO FIREARMS SHOOTERS CAUTION THE UNIQUE RECOIL IMPULSE OF A SPRING/GAS PISTON POWERED BARREL AIR RIFLE WILL DAMAGE RIFLE SCOPES DESIGNED FOR FIREARMS – EVEN FOR HEAVY CALIBER FIREARMS. IT IS RECOMMENDED TO ONLY USE SCOPES LIKE THE SIG WHISKEY3 ASP THAT ARE SPECIFICALLY DESIGNED FOR SPRING POWERED AIRGUNS.
