Is it safe to load 50 or 55 gr. in the 5.7 case to shoot in the 5.7 Ruger pistol? I have true blue and auto comp powder, thanks for the help

You can, but the Ruger generates chamber pressures a little higher then the Five Seven.

Keep in mind the 5.7x28mm performs best with rounds at or below 40gr.

50 is the limit to avoid excessive wear if you are loading full power rounds.

The below 40gr have plenty of knock down power by way of speed.

Folks regularly one shot stop feral hogs at a dead run and deer with 5.7 SS197 and EA's T6B's.

EA's Pro2 uses a 50gr Bliztking, That said it's almost sub sonic and will give PS90's fits and is limited to pistols.
While I have tested thousands of rounds through the Ruger 57 that has been T6B and S4 since that is all we are running right now since folks don't want our milder in EA terms ammo. I have not tested our Pro2 in the Ruger yet.
