The Maxim M/32-33 is a Finnish modification of the Russian M1910 Maxim, developed by Aimo Lahti in 1932. The weapon was able to fire at the rate of 850 rounds/min, while the Russian M1910 and earlier Finnish M09-21 were capable of 600 rounds /min. The reason was not only that Aimo Lahti was ordered to develop the weapon with a new metallic ammunition belt but also because of other improvements, such as accelerator mechanism and muzzle booster. Other improvements had Maxim M/32-33's whole handle part were redesigned and installation point for optical sight was added.

Unlike all the other Finnish Maxims, the Maxim M/32-33 was designed to be suitable for anti-aircraft usage from the beginning. Tripod M/32 was designed and issued with extra parts allowing it to be easily modified as an anti-aircraft mount and accessories for anti-aircraft shooting were included.

The last improvement to the M/32-33 was adding a snow filling cap to the water jacket, this way snow could be used instead of water in winter, so there was no need to carry and taking care of 3 kg of coolant water in winter. This feature was copied in the late Russian World War II Maxim variant.

Some few hundred early M/09s were modified into M/32s by Gun Depot 1 between 1933-1935. These weapons have also been called M/09-32s.
