 Russians also tended to modify the Type 38's magazine latch, as it was found that gloved hands would sometimes inadvertently nudge the magazine release and dump the ammunition.In 1914, approximately 150,000 Arisaka Type 30 and Type 38 rifles and carbines were sold to British forces (mainly to the Royal Navy), where they were used for training.The 6.5×50mm round was subsequently produced in Britain by the Kynoch company and was officially adopted for British service as the caliber Mk II in 1917.
