2. Rotate the trigger guard group towards and into the
receiver opening, until it is parallel with the receiver.
3. Align the trigger guard group with the hole in the
receiver and install the trigger guard pin from the RIGHT
side of the receiver (ejection port side) until it is flush
with both sides of the receiver. The pin should pass
through easily with little force. If significant resistance is
felt, remove the trigger group and repeat step one above.
Your Model 1300 shotgun is now fully assembled.
Immediately confirm that the safety is in the “ON SAFE”
position. Take time to wipe down and clean all external
surfaces as explained under Cleaning and Maintenance

SIGHT ADJUSTMENTS
Some Model 1300 shotguns are fitted with rifle-type open
sights. The style and adjustment system may vary
between models and grades. The proper procedure is to
shoot a group with the sights set as they come from the
factory (intermediate position on both elevation and
windage), and then make incremental adjustments to
move the sight blade and blade holder to position the
group on your target. The procedures below are for the
most common type of open sights found on Model 1300
shotguns.
BEFORE MAKING ANY SIGHT ADJUSTMENTS,
MAKE SURE YOUR SHOTGUN IS FULLY
UNLOADED AND THE MUZZLE IS POINTED IN
A SAFE DIRECTION. PLACE THE SAFETY IN
THE “ON SAFE” POSITION.
UP OR DOWN ELEVATION ADJUSTMENTS.
Adjusting elevation on your Model 1300 requires you to
lift up the rear notch blade on your shotgun’s rear sight
with your fingers and move the notched elevator either
forward or backward. To raise point of impact, use your
fingers to lift up on the blade and slide the elevator rear-
ward. Adjusting the sight to make your gun shoot lower is
just the opposite — move the elevator forward.
Remember:
• Move the blade up to shoot higher.
• Move the blade down to shoot lower.
RIGHT OR LEFT WINDAGE ADJUSTMENTS.
On most Model 1300 sights, the entire rear sight blade
holder is dove-tailed in the rear sight base. To adjust for
windage, gently move the rear sight blade to the right by
tapping at the dove-tail using a wood dowel or similar
