I have a M91/30 and a M44. I haven't fired either one yet. (Cleaning cosmoline has become my most recent passtime).
The M1938 is between the M91/30 and the M44. Same ammo, same low price, same basic appearance. I think I'm gonna have to get one. (Not to round out the set, but to give me some more cosmoline to clean off
).
