Conceived during World War I as being more a powerful weapon than those arming contemporary foreign destroyers. Its superiority was more theoretical than real, as it had a slow rate of fire for a destroyer weapon and was difficult to load at low angles of elevation. Used a Welin screw breech mechanism.
It had been planned to replace these guns with the 138.6 mm Model 1923, but lateral stability problems prevented the change.

- ^Dye was introduced about 1938 with red issued for the lead ship in the flotilla, green for the second and white (later yellow) for the third.
- ^The Tigre class were originally to have six guns. The magazines were not reduced in size when this was changed to five guns which explains the difference in the ammunition stowage between this class and the follow-on Simoun class.
- ^All guns except the amidships gun on the Tigre class were given ready-use stowage for 24 rounds. Due to the separation of the amidships gun from the magazines, this mounting was given 30 ready rounds.
- ^The Tigre class carried 398 projectiles and 468 charges in the forward magazine and 404 projectiles and 418 charges in the after magazine.
- ^The Simoun class magazines carried a total of 440 projectiles, 462 charges and 68 practice rounds.

|19,700 yards (18,000 m)||(45 mm)||---|
This data is from "Destroyers of World War Two" and "French Destroyers."

This data is from "Warships after Washington" which notes that the low muzzle velocity of this gun made it inaccurate at long ranges.

During refits in 1943 and 1944 the gun sight ports on the few surviving destroyers were enlarged and new cross-hair type sights fitted to facilitate barrage fire against aircraft up to the full elevation of 36 degrees. Time-fuzed ammunition was supplied with the fuzes being set before loading.
- ^A twin mounting, Model 1921, was planned but trials aboard the sloop Amiens showed that these were cramped and difficult to work as the loaders interfered with each other. Rate of fire was was significantly less than two single mountings and the weight was nearly the same.
- ^The amidships gun on the Tigre class was supplied from the aft magazine hoists.
- ^Following the cancellation of the 138.6 mm Model 1923 replacement program due to top-weight stability problems, modest improvements were made to the Model 1919 mountings. An automatic loading tray was fitted to increase the firing rate and a raised circular platform was added for the loaders. Stability problems persisted and led to the removal of No. 4 gun from most of the Simoun class in 1940. However, following the Armistice, these guns were re-installed during 1941 and other equipment including DCT on some ships was removed.
- ^The guns originally had only light shields but these were replaced with more substantial "wrap around" shields shortly after completion to provide the crews better protection from spray and splinters. These added about 2.46 tons (2.5 mt) to the mounting weight.
- ^Originally the mountings were to have a lower maximum elevation, but they were redesigned to raise the trunnions to 59 inches (1.5 m) in order to increase the maximum elevation to 36 degrees. This change did hamper working the gun at low elevations as the heavy projectiles were difficult to lift up to the breech. Ammunition was supplied by electrically-powered chain hoists which delivered both projectiles and cartridges horizontally.
