The mle 1887/1893 guns were typical built-up guns of the period with several layers of steel reinforcing hoops. The guns used an interrupted screw breech and fired separate loading bagged charges and projectiles. The two designs were similar in construction and performance, the main difference between the two models being their weight 37.6 tonnes for the 1887 and 35.4 tonnes for the 1893. The later Canon de 274 modèle 1893/1896, despite being shorter, used a larger propellant charge which gave them higher muzzle velocity and range.
