To match the M2 in range it would have to be 450m (i.e. 1.8km maximum effective range) so anyone wanting to make it more realisic should probably up the range to that and probably make it d10+5 damage. That would solve most complaints about the weapon not having enough power I think.
If you want another weapon with the SAW role here is what I would recomend assuming you changed the Heavy Stubber. Note that it needs a proper 40k name but I cant think of one atm.
The SAW is and underused concept in the Imperial Guard with most regiments not seeing the need for a weapon that puts out comparible damage to a las gun when there is the reliable Heavy Stubber that provides much more punch. A few regiments that emphisise mobility and squad level operations though find them invaluable for the increased firepower they provide. Although not a common sight outside of the Imperial Guard they are occationally picked up by underhive gangs where thier massive rate of fire combined with thier accuracy make them a deadly proposition for those gangs that rely on the more conventional heavy stubber that requires time to set up. More than a few gangs have met thier grisly end after being ambushed by the SAW.

Suppressive Weapon: The rate of fire of the SAW makes it very useful as a suppressive weapon combined with the accuracy when using Suppressive fire the SAW gains an additional hit for each degree of success rather than 2 degrees of success.
Manstopper: Because the SAW uses normal rifle ammunition manstopper rounds may be used with this weapon
