TARGET SHOTGUN
This firearm was originally sold with a key-operated locking device. While it can help provide secure storage for your unloaded firearm, any locking device can fail. All guns are designed to fire if they are loaded and the trigger is pulled. Therefore, never install the
locking device inside the trigger guard or in any way that it can possibly pull the trigger! Do not
leave the keys in the lock. The ultimate responsibility for
secure storage of any firearm must depend upon its owner and his or her individual circumstances.
Guns should be securely stored unloaded, in a secure location, separate from their ammunition.

FIREARMS ARE DANGEROUS WEAPONS–
READ THE INSTRUCTIONS AND WARNINGS
IN THIS MANUAL THOROUGHLY AND
CAREFULLY BEFORE USING.
GENERAL INFORMATION
AND MECHANICAL CHARACTERISTICS
The RUGER®TRAP MODEL shotgun which you have selected is a single barrel, single shot, 12 gauge shotgun specifically designed solely for the clay tar
get sport of trapshooting. As such, it has many specialized features and characteristics not found in other shotguns designed primarily for field shooting and hunting. You
must thoroughly familiarize yourself with its mechanical characteristics and safe handling procedures prior to ever taking it onto a trap field. It is strongly recommended that this shotgun only
be used for trapshooting, due to its
specialized mechanism and features.
Specialized features demanded by target trapshooters and found in the RUGER
®
TRAP MODEL Shotgun include:
A target trigger, adjustable for weight of pull (see p. 29).
An adjustable rib, which can be set for individual shooters’ stature, sight
picture, stance, and other preferences (see p. 26).
A two-bead sighting system located atop the adjustable rib (see p. 27).
WARNING–ALTERATIONS
This product was designed to function properly in its original condition. Alterations can make it unsafe. Do not alter any part or add or substitute parts or accessories not made by Sturm, Ruger & Co. Inc.

A wide, cut-checkered beavertail forend for consistent front hand
positioning.
A target-style pistol grip of special shape and contour.
An adjustable buttstock comb, to accomodate various facial configurations,
stances, and hold-over for rising trap targets. It also is laterally adjustable for “cast off” and “cast on” (see p. 28).
An adjustable buttpad, which can be set by the shooter for length of pull
and “cant” (the angle of the buttstock from the center line of the stock to the left or right, as desired) (see p. 27).
Since single barrel trap guns are never loaded or closed until immediately
prior to a shooter calling “pull” to fire at a clay target (and are opened immediately after firing or if firing is delayed) trap guns generally have
no separate manual safety/bar
rel selector (see p. 15). There is no
possibility that the shooter will be unable to fire due to forgetting to correctly move the safety to the “fire” position for each shot during an extended target competition tournament.
Another special feature of the Ruger Trap Model shotgun is its straight
grooved “controlled pattern” bore. It prevents rotation of the wad and shot
column while they move down the bore when fired. This minimizes shot dispension and contributes to improved pattern density on targets at all ranges. The 34” long barrel is also “back-bored” with a long forcing cone, which contributes to lessening felt recoil and fatigue. This is especially important to trapshooters, who routinely fire at hundreds of clay targets during a match. It accepts the latest screw-in Ruger choke tubes, and is supplied with “full” and “modified” choke tubes for trapshooting (see pp. 13
- 14).
THE BARREL ASSEMBLY
The barrel is silver soldered to the monoblock at the chamber portion of the barrel. The adjustable ventilated rib is hinged at the rear and is securely clamped to two barrel bands soldered to the barrel. The barrel bands have a dovetail on top that the rib clamps are dovetailed into, allowing the rib to slide in these dovetails as the barrel heats up from shooting. The rib also features a two gold bead sighting system for alignment prior to shooting.
The trunnions (on which the barrels pivot) are mounted high, close to the centerline of the barrel, and are integral with the receiver.
In addition to trunnions, a massive square lug at the bottom rear of the monobloc locks into the thick bottom wall of the receiver to provide extra security for the barrel-to-frame lock-up.
Projecting from the rear end of the barrel assembly, one on either side, are two heavy, integral heat-treated lugs which are engaged by the locking bolt as it slides forward when the gun is closed. The locking bolt is, in effect, a wedge, due to the angle of the locking faces. These faces have more than adequate area and are hardened and precision-ground to resist wear.
7
The automatic ejector assembles to the monobloc simply, without retaining pins or screws. The ejector sear is pivoted on an integral stud in the forend iron and provides positive ejection to throw the empty fired shell casing from the chamber when the action is opened. Note that it does not eject unfired live cartridges, but merely extracts them partially from the chamber for manual removal (see “To Unload”, p. 16.)
THE STOCKS
The buttstock and forearm are made from first quality straight grain American walnut, fully seasoned, with deep-cut checkering of 18 lines to the inch. The specially shaped buttstock is fully adjustable for length of pull, comb height, cast-off, and cast-on. The forend is of wide “beavertail” target configuration. All wood surfaces are sealed with a satin weather-resistant finish.
Provision is made in the buttstock for the through-bolt system of attachment which is strong and simple. The rear ends of the tangs interlock with the wood and the forward end of the stock is tenoned into recesses in the receiver to provide maximum strength and resistance to splitting or loosening.
The RECEIVER securely
locks the barrel into a low,
direct line with the hands
to minimize felt recoil and
maximize pointability.

NOMENCLATURE - RUGER TRAP MODEL SHOTGUN
The BUTTSTOCK is held on the gun
by a long through-bolt, which is
accessible only after the recoil pad
base plate on the end of the buttstock
is removed. It is adjustable for length
of pull from 13 1/2” - 15 1/2”.
The TOP LEVER and its massive pivot are
one integral component directly engaged
with the locking bolt on both opening and
closing motions.
The PISTOL GRIP is finely cut-
checkered and is of special
target style and contour.
The MONOBLOC securely
locks the barrel/rib assembly
into the receiver.
The TRIGGER is set at the
factory at a 3 - 4lb. trigger pull.
This can be adjusted to some
degree. (See pp. 29 - 31)
The TRIGGER GUARD
protects the trigger from
inadvertent contacts
which could cause the
gun to discharge.
The COMB of the stock is
adjustable for height, cast-off,
and cast-on.
The BUTTPAD is screw-
adjustable for “cant”.
The VENT RIB can be
adjusted for height and is
free to float as the barrel
expands.
The special low mounted “controlled
pattern” trap BARREL is hammer
forged stainless steel, back-bored,
with screw-in chokes. (Not seen in
this view)
The finely checkered
beavertail FOREND is
designed to afford a
comfortable grip for the
pointing hand.

OTHER FEATURES
The RUGER®TRAP MODEL shotgun has its receiver, the trigger, forend iron, and barrel made of stainless steel with an attractive brushed finish. The trigger guard, top lever, monobloc, and barrel components are of heat-treated chrome-molybdenum steel, polished overall and blued.
The top lever and its massive pivot are one integral component directly engaged with the locking bolt both on opening and closing motions. The lever and the locking bolt are driven to the closed position by the top lever spring which, through its strut, retains the top lever in the gun. The Ruger shotgun has been engineered to minimize the force required for barrel opening and cocking through a patented “easy opening” system.
AMMUNITION
The RUGER®TRAP MODEL Shotguns have 2 3/4” chambers and may be used with all standard commercially manufactured 12 gauge 2 3/4” shells. Do not attempt to use 3” or 3 1/2” shells, as they will not fit correctly into the chamber and could create excessive pressure if fired. Best results are usually obtained by using factory ammunition specifically designed as “trap loads” for this specialized form of clay target shooting. This gun has been tested with special proof test ammunition which conforms to U.S. industry practice. It is intended for use only with standard ammunition of the proper gauge, loaded to U.S. Industry standards. Use of incorrect ammunition can destroy any gun and result in
serious injury to the shooter or bystanders, (See “Ammunition Warning” and “Ammunition Notice,” p. 10).
Shotgun cartridges are often called “shotgun shells” or “shotshells”, and these terms will be used interchangeably throughout this manual.
STEEL SHOT
All steel shot loads loaded to current U.S. industry specifications can be used in all currently manufactured Ruger shotguns equipped with screw-in chokes.
Steel shot generally patterns tighter than conventional lead shot loads. Modified choke tubes generally deliver “full choke” patterns when used with steel shot.
We do not recommend any of our shotguns for use with reloads, steel shot or otherwise, as we have no control over their components or loading procedures used (See “Ammunition Warning” and “Ammunition Notice,” p. 10).
Death, serious injury, and damage can result from the use of wrong ammunition, bore obstructions, powder overloads, or incorrect cartridge components. Always wear
shooting glasses and hearing protectors.

ASSEMBLING THE SHOTGUN
The RUGER®TRAP MODEL Shotgun is shipped partially disassembled. To assemble, proceed as follows:
1. After unwrapping the barrel/forearm assembly and receiver/stock assembly,
wipe excess rust preventative oil from the monobloc and inside surfaces of the receiver. Swab the bore with a clean cloth patch on a cleaning rod to remove any excess oil.
DO NOT ATTEMPT TO JOIN THE BARREL ASSEMBLY TO RECEIVER WITH THE FOREND ATTACHED!
2. To Remove Forearm From Barrel Assembly (See Figure 2):
a. Unlatch forearm by pulling down on latch lever. b. Carefully pull down on tip of forearm until slight resistance is felt -
APPLICATION OF EXCESSIVE FORCE AT THIS POINT CAN RESULT IN BREAKAGE.
c. While holding forearm tip away from the barrel, carefully pull forearm
toward the muzzle and remove forearm from the barrel.
Figure 2
3. To Attach the Barrel Assembly to
the Receiver:
Hold the stock by the pistol grip in one hand as shown in Figure 3. Make sure the top lever is opened to the right in order to accept the barrel assembly. Hold the barrel assembly (without
the forend) in the other hand and engage the integral trunnions in the receiver with the corresponding recesses at the front end of the monobloc. Be sure the small lug (indicated by the arrow in “A” in Figure 3) on the outer surfaces of the ejector engages its corresponding slot inside the front end of the receiver BEFORE CLOSING
THE GUN! The foregoing caution must be followed or the receiver will be damaged by the ejector as the gun is closed.

4. Swing the muzzle end of the barrel upward, pivoting the rear end of the monobloc downward to seat in the receiver as shown in Figure 4. The barrel assembly is seated and locked into the receiver when the top lever snaps to its centered position.
5. Push the rear end of the forend iron back over the ends of the ejector as shown in Figure 5. Then carefully swing the front end of the forearm upward until the forend latch lever catches the forend latch hook on the underside of the lower barrel, and the forend assembly snaps into its locked position flush with the stock.

INSTALLATION OF SCREW-IN CHOKE INSERTS
Make sure the shotgun is unloaded! Either open the action or dismount the
barrel completely from the action assembly. Lightly coat the threads of both the barrel and the desired choke insert with good quality gun oil. Carefully start the choke insert into the barrel threads by hand, taking care that the choke insert is not cross-threaded. Using the choke wrench (supplied), carefully hand-tighten the choke insert into the barrel until it is tightly secured in the barrel, so that the choke insert is fully bottomed into its recess in the barrel. Take note which choke you are inserting into the barrel. The trap choke inserts are stamped either “FULL” or “MODIFIED”. Remove the choke wrench from the barrel after tightening.
CHOKE WRENCH
CHOKE INSERT
("TUBE")
34"
"CONTROLLED PATTERN"
BARREL
NOTE: Stainless Steel trap choke inserts may protrude slightly from muzzle when fully seated. This is normal and helps protect the muzzle of the barrel from damage.
To minimize the possibility of damage to the screw-in choke inserts and the barrel threads, it is recommended that a choke insert be kept correctly tightened into the barrel at all times, including storage and cleaning. Cleaning the barrel without the choke insert in place can push dirt and other fouling into the barrel threads, which will interfere with proper installation of the choke insert.
Be sure you only use the correct choke insert (tube). The screw-in choke inserts
for the newer Ruger “easy open” shotguns, including the Ruger Trap Model shotgun, are stainless steel and stamped on the side either “FULL” or “MODIFIED”. They are not interchangeable with the shorter, blued steel choke tubes of older Ruger shotguns which have identification slots on their muzzle end. A general rule of thumb is that if the choke tube screws in significantly below flush with the muzzle, or if the choke sticks more than slightly out of the muzzle when completely tightened, you are using the wrong choke tube!
Steel Shot — Steel shot loads manufactured to U.S. Industry Standards can be used with Ruger Screw-in choke inserts with no special precautions other than those listed above. (See “Ammunition” and “Steel Shot” instructions and warnings, pp. 9 - 10).

Do not peer directly into the shotgun muzzle!
This is dangerous and unnecessary. Do not change choke insert in a loaded shotgun. Never fire the shotgun if a screw-in choke insert is not fully and tightly bottomed into the barrel threads, or if the insert is improperly installed or “cross-threaded”, or if the threads of either the barrel or the choke insert are damaged. Under these conditions, the barrel will be damaged and the screw-in choke insert can be propelled out of the muzzle with great velocity when the gun is fired, with resultant risks of property damage or injury to the shooter or bystanders. Do not attempt to alter or modify existing fixed choke Ruger shotgun barrels for screw-in choke inserts. This can seriously weaken the barrel and may be dangerous. See “Alteration Warning” elsewhere in instruction manual.
DO NOT PEER INTO MUZZLES
OR CHANGE TUBES ON A
LOADED SHOTGUN
WARNING –SCREW-IN CHOKES
OPERATION OF THE SHOTGUN
Always check to be sure the gun is unloaded before handling, “dry-firing”, take­down, cleaning, or storage.
Every RUGER®TRAP MODEL Shotgun is inspected before shipment to ensure that it conforms to our standards of finish and performance. WE ASSUME NO RESPONSIBILITY FOR ANY INJURY OR DAMAGES RESULTING FROM ITS INTENTIONAL OR ACCIDENTAL DISCHARGE. No mechanism can prevent injury caused by careless or thoughtless handling of a loaded firearm. (See “The
Basic Rules of Safe Firearms Handling”, pp. 39 - 42)
Never fire the shotgun without a correct screw-in choke insert in place. Doing so
will cause an erratic shot pattern and may irreversibly damage the choke insert threads in the barrel, making correct installation of the screw-in choke inserts impossible without expensive re-barreling. Do not attempt to use screw-in choke tubes of any other make or manufacture in Ruger shotguns. They will not function properly.
