The wooden parts in grade 3 walnut are hand-finished according to the requirements of the individual customer (oil, wax, tru oil® etc.). The stock may be adapted according to the customer's specifications. The checkering on the stock and the forend is designed for maximum grip and is done entirely by hand.

The design of the top lever is the result of collaboration with leading shooters. It improves the grip, reduces effort and makes it easier for left-handed shooters.

The simple, automatic trigger group release procedure consists of three distinct, practical movements that may be performed when the firearm is in the condition of maximum safety, i.e. when it is open. The position of the trigger may be easily regulated and with a high degree of precision.

The DT11 Anniversary receiver has been tempered and engraved with a floral motif that evokes the modern style that has also been adopted for the SL3 and 687 EELL Classic. The pins, top lever and ribbons framing of the side plates are engraved with a floral motif, while the side plates are hand polished for a prestigious mirror effect. The base plate of the receiver features floral engraving on the lateral sections, while the polished central area contains the Beretta and DT11 logos, complete with the inscription “10th Anniversary Limited Edition”. The receiver base plate is also embellished with the specific production number of the individual piece, hand engraved and gold inlayed. This number is also indicated in the serial number.

Thanks to its unique manufacturing process, Steelium represents the barrel production technology that enables Beretta tri-alloy steel to become a true ballistic gem. Deep drilling, cold hammer forging and vacuum relieving provide the steel with mechanical characteristics that are ideal when superior ballistic performance is required. The Steelium Pro barrels mounted on the DT11 represent the last word in Berretta Steelium gun barrels and boast an internal tube profile with a highly elongated progressive triple cone, which varies according to the length of the barrels, up to a maximum length of 450 mm from the muzzle (in the case of 76 cm barrels).

The carefully chambered barrels and the upper profile of the receiver fences permit rapid target acquisition even during instinctive shouldering movements.
The various component weights are distributed so that the centre of gravity is aligned with the first barrel: This feature practically eliminates muzzle rise, enabling faster target acquisition for the second shot.

The top rib features newly designed, hollow barrel bridges. This improves barrel balance and improves heat dissipation when the tubes overheat.
