At the time, the unit was equipped with 210 millimetres (21 cm) mortars and 149.1 millimetres (14.91 cm) cannons. By 1921 the regiment was motorized and 155 millimetres (15.5 cm) howitzers were added. In 1934, the unit was moved to Gora Kalwaria.

In 1938, the 155 millimetres (15.5 cm) howitzers were handed down to the heavy artillery regiments. During the Invasion of Poland in 1939, one out of three battalions was assigned to Armia Modlin, and two battalions to the 38th Infantry Division (Poland).[1]
