MG38: Colt's Interwar Water-Cooled Machine Gun (Ad-free)
🕑 Added 2025-05-07 12:00:03 +0000 UTCAfter World War One, Colt was the sole owner of license to produce Browning machine guns. With production tooling well established form the war, the company set about looking for international sales. The water cooled .30 caliber (the M1917 in US service, essentially) was designated the Model 1919 Automatic Machine Gun. In 1931, it was renamed the MG38, although basically the same gun as in 1919. It had a few distinctions from the US military pattern, including:
- Manual safety on the backplate
- Self-contained recoil spring
- Large water fill and drain fittings, identical to the ones used on Colt’s .50 caliber guns
- Slightly different top cover latch
Colt offered the guns with lots of options and features, including a variety of calibers (basically any modern rifle cartridge of the time), flash hiders, lightened anti-aircraft bolts, and spade grips (guns sold with spade grips were designated MG38B). From 1919 until commercial production ceased in January 1942, Colt had sold 2,720 water-cooled Brownings in total. Most went to South America in 7.65mm, with Argentina being the single biggest buyer.

The Norwegian Army used a Colt machine gun in calibre 6.5 x 55 in the interwar period, and went to war with it in 1940. Were these made and delivered by Colt USA, or made under license in Norway?

Yes - Britain made extensive use of .303 caliber Brownings as aircraft armament during WWII.

Question about the chamberings that Colt would accommodate: Could the MG38 (and by extension all Browning style machine guns) be adopted to use rimmed cartridges like British .303 and 7.62 x 54R?
