What does (1M) on HPI product item mean?

This maybe a dumb question but I see (1M) on quite a lot of Savage products. Like 49t spur gear(1M) etc. Anyone want to enlighten me feel free.

Thanks Jam 1, your rite, just looked it up and it does relate to the pitch of the gear. Another brain taxing question answered, now I have space for another.
