The L5 IMB configuration uses an aluminum frame with a black steel slide and barrel to deliver the lighter L5 profile in .357 Magnum. The 5-inch barrel integrates a multi-port muzzle brake, with additional porting and lightening cuts that define this specific model variant.
This Mark XIX retains the platform's signature operating system: gas-operated with a rotating multi-lug bolt, single-action only, and hammer-fired. It includes an ambidextrous slide-mounted manual safety with a red fire indicator and black wrap-around rubber grips with finger grooves.
Aim and mounting features include a green fiber-optic front sight and an adjustable rear blade with an elevation screw. A full-length top Picatinny rail is machined into the barrel/shroud assembly; the slide top is smooth. The dustcover remains smooth with no bottom accessory rail.
Capacity is 9+1 in .357 Magnum. This U.S.-made L5 uses 5-inch components that are specific to this configuration; L5 5-inch parts are not interchangeable with 6-inch or 10-inch Desert Eagle components. Mfg. Part Number: DE357L5IMB.
