Sounds much better, though I doubt it will be changed, even if it is such a minor thing. Anyway, I'm guessing lots of others prefer the current sound.
although i do indeed find a lot of the mod sounds cooler sounding. For ostfront all the sounds of weapons were recorded from the actual weapons itself, and if not available from a comparable weapon.
