That is correct. The Pulsar C and VX6-7 are straight upgrades from the default Solstice. The only real difference between the Pulsar C and VX6-7 are the rate of fire and cert upgrades. I think the VX6-7 upgrades (soft point ammo and double laser) tend to make it a great short range from the hip and good medium range. The Pulsar C upgrades (high velocity ammo and double grip) tend to make it perform good at short, great at medium, and okay at long. That said, has anyone messed arounf with the Solstice SF yet? The amount of cert options on that gun are insane.
