i can give you a more detailed answer tomorrow, but from memory of what i was reading in a small arms of the world book last nite , russia adopted an m10 in 1910 which is the same caliber as the 1910 and the m38, m44. it was a bayonetless precurser to the m38...but it was not an m38. and it is called an m10. i had not heard of this before but am hardly knowledgable about russian arms. as an aside, i bought a m44 with a laminated stock, and it is a work of art. i was thinking of adding a m38 but the m10 caught my eye.
