– 69 – ELEGANT AND STURDY CASE. Entirely hand executed by master craftsmen, the case of the Beretta SO10 over-and-under is made of solid wood covered in resistant leather. It features reinforced corners, safety slings and key locks. A full range of hand-made cleaning and maintenance accessories is provided, each with its own separate compartment.
– 70 – ASSEMBLY Fig. 7 Fig. 8 ! NOTICE:In order to preserve the wood and metal surfaces from the possibility of corrosion and scratching, it is recommended to wear cotton cleaning gloves before handling any part of the Beretta SO10. It is also advisable to handle the shotgun over a soft and smooth surface. The beautiful walnut grain is enhanced by multiple, hand-applied, layers of oil, wax and Tru-Oil ®(upon request). The surfaces of the stock and fore- end can be subject to scratching or marring if not properly handled and stored. Similarly, the metal parts (barrels and receiver) are susceptible to the moisture and acidity of the hands. •Remove the fore-end from the barrels by pulling the fore-end catch lever down (Fig. 7). WARNING:Do not attempt to assemble the barrels on the receiver with the fore-end attached! •Wipe excess rust preventative oil from the barrels and the inside surfaces of the receiver. Swab the bores (the inside of the barrels) with a clean cotton patch held on the supplied cleaning rod .
– 71 – CAUTION:The hinge pin and the locking areas are very important mating surfaces. The receiver, the barrels and the fore-end iron are subject to very high loads. Improper lubrication of these components can cause seizing of parts or malfunctioning of the shotgun. (The areas to lubricate are indicated by the arrows on Fig. 8). Before using the shotgun, make sure that lubricant is present as instructed. NOTICE:It is recommended to use Beretta-Interflon ®lubricant with Teflon®(code OL38) or high quality gun lubricants exclusively. Such products are available at fine gun dealers. •Push the top lever to the right. When barrels are not assembled on the receiver, the top lever remains locked in the open position (right) (Fig. 9). CAUTION:The top lever must be in the open position before the barrels are assembled. Failure to do so will cause damage to the ejectors.

– 72 – Fig. 12 Fig. 11 •Insert the barrels inside the receiver so that the hinge pins of the receiver fit into the corresponding slots in the barrels (Fig. 10 page 71). Be sure the small lugs of the ejectors (see arrow in Fig. 10)engage their corresponding slots in the receiver before closing the gun. •Swing the barrels upwards smoothly and evenly. When the top lever snaps to its centered position, the barrels are locked into the receiver (Fig.11). •Fit the fore-end onto the barrels, first inserting the two fore-end iron levers in the slots on the side walls of the receiver (Fig. 12). Swing the fore-end upwards (Fig. 13). Place the fore-end iron (the curved steel component at the rear of the fore-end) over the ends of the ejectors against the front part of the receiver so that the fore-end slides into position under the barrels (Fig. 14). •Press forcefully to allow the fore-end latch to catch the barrel hook. The operation is done correctly when the fore-end catch lever is flush with its seat (Fig. 15). •Run a soft, lightly oiled patch over the surface of the shotgun to remove any finger prints or dirt.
– 73 – Fig. 14Fig. 15 Fig. 13 NOTICE: Once the shotgun is handled, always and accurately clean all external surfaces (wood and metal) with a soft and clean patch in order to preserve the delicate finishes over time. The Beretta Cleaning Cloth (FAW08), available at fine gun dealers, is specially designed to clean your fine shotgun. Poor handling and cleaning of the firearm could compromise your Beretta warranty.
– 74 – At various points in this manual you will be instructed to visually check the cartridge chambers of the Beretta SO10 shotgun to be certain this is unloaded. This should soon become second nature to you, as should the following precautions: •Never assume that a firearm is unloaded. •Never point or push a firearm toward yourself or another person. •Always visually check to see that the chambers are unloaded. •Engage the safety and open the shotgun by pushing the top lever to the right before handing the gun to another person. •Never take or pull this shotgun from another person unless the safety is engaged, the barrels are pivoted downwards and the chambers have been visually checked to confirm that the firearm is completely unloaded. To visually check to be certain the cartridge chambers are empty, carefully follow the steps below. WARNING:Keep your finger OFF THE TRIGGER and the barrels pointed in a SAFE direction. •Engage the safety by pushing the safety lever all the way rearwards. In this position the marking “S” is fully visible (Fig. 1, 3, 5 page 61). WARNING:When the safety lever covers the marking “S” the manual safety is DISENGAGED and the firearm is in the FIRE position (Fig. 2, 4, 6 page 61). •Push the top lever to the right and open the shotgun by levering the barrels downwards. •Check the chambers to be certain they are empty. CHECK THE GUN IS UNLOADED ! !
– 75 – If the shotgun is unloaded, proceed to the following step, otherwise refer to the procedure: “UNLOADING THE SHOTGUN”. •Swing the barrels upwards to close the shotgun. When the top lever has fully moved to its centered position, the barrels are correctly closed in the receiver. WARNING: THE HAMMERS ARE COCKED. Keep the barrels pointed in a safe direction and decock the hammers by following the instructions of the next paragraph. NOTICE:Once the shotgun is handled, always and accurately clean all external surfaces (wood and metal) with a soft and clean patch in order to preserve the delicate finishes over time. The Beretta Cleaning Cloth (FAW08), available at fine gun dealers, is specially designed to clean your fine shotgun. Poor handling and cleaning of the firearm could compromise your Beretta warranty. ! WARNING:Always be certain that the shotgun is unloaded. Please refer to the instructions given in the previous paragraph. WARNING:Always keep the shotgun pointed in a safe direction. Once the top lever is engaged, and the shotgun has been opened to check that it is unloaded, or for unloading or for inspection of barrel obstructions, the hammers are cocked. Decock the hammers when the gun is unloaded, using the procedure described below, to allow the springs to remain in an uncompressed state. CAUTION:It is important not to decock the hammers on an unloaded gun without the use of snapcaps to avoid the possibility to damage the firing pins. DECOCKING THE HAMMERS ! !
– 76 – DRY FIRING/SNAP CAPS Dry firing is defined as firing a firearm with no cartridges in the chambers. The snap caps supplied with the Beretta SO10 shotgun are inert chamber inserts that allow the gun to be dry-fired without damaging the firing pins. •Open the gun. •Insert snap caps into the chambers (Fig. 16). •Pull the trigger to decock the first hammer. •Push the selector to the second position. (On some models this is not possible since the selector is blocked by a screw.) NOTICE:If the shotgun features a SINGLE NON-SELECTIVE TRIGGER or a SELECTIVE, BLOCKED TRIGGER (inertia mass type) it is necessary to push the safety lever all the way rearward (safety engaged) and then push it forward (safety disengaged) to prepare the firearm for decocking the second hammer. •Pull the trigger to decock the second hammer. To take out the snap caps without recocking the hammers: •Remove the fore-end. •Lever the barrels downwards only as much as required to take out the snap caps. NOTICE:An excessive opening of the barrels could cause the separation of the barrels from the receiver. •Close the gun and replace the fore-end. Fig. 16
– 77 – Visually check the barrels to be sure there are no obstructions in the chambers and bores (the inside of the barrels). This is extremely important because if a cartridge is fired into an obstructed barrel, a catostrophic failure can result. WARNING:Always be certain that the shotgun is unloaded. Please refer to the instructions given in the “CHECK THE GUN IS UNLOADED” paragraph. •Push the top lever to the right and rotate the barrels downwards to open the shotgun. •Look down each barrel from the muzzle (or front end) so that you can see completely through the barrel to make sure no obstruction exists. If an obstruction in the barrel is detected, a qualified gunsmith must remove the obstruction and inspect the shotgun before it can be fired. NOTICE:Once the shotgun is handled, always and accurately clean all external surfaces (wood and metal) with a soft and clean patch in order to preserve the delicate finishes over time. The Beretta Cleaning Cloth (FAW08), available at fine gun dealers, is specially designed to clean your fine shotgun. Poor handling and cleaning of the firearm could compromise your Beretta warranty. CHECKING FOR OBSTRUCTIONS !
– 78 – AMMUNITION (CARTRIDGE) NOTICE:Beretta assumes no responsibility for physical injury or property damage resulting from the use of defective, improper, hand-loaded, reloaded or remanufactured ammunition. Serious damage and injury, and even death, could result fromt he use of incorrect ammunition, from firing against bore obstructions and from propellant overloads. Use of reloaded ammunition will void the manufacturer’s warranty. Use only high-quality, commercially-manufactured ammunition. Be certain that the cartridge is the appropriate gauge and loading for the shotgun and is clean, dry, and in good condition. WARNING:Carefully inspect each cartridge before it is inserted in the chamber. Be certain the cartridge cases are not split, deformed, or the cartridges do not possess any other dents or defects (this applies even to factory ammunition). You will find the markings for the gauge, chamber length and type of chokes for your shotgun on the side of the barrels. This shotgun has been tested with special proof test ammunition. WARNING:Never use cartridges that do not correspond to the markings on the side of the barrels. WARNING:Only use cartridges that are the same length or shorter than the length of the chambers indicated on the side of the barrels. AMMUNITION ! ! ! !
