First time doing a 3 piece shower drain. Is this 1/8" gap

[raider1v1]

This was my first time doing a 3 piece drain. Between measuring for the depth of the drain, subfloor and slope, i have about a 1/8" gap between the shower drain piece and the PVC pipe thats solvent welded into it. All of the rest of my connections i was able to get to seat 100% into the coupling.

Do i need to tear this out and redo it?

It will be fine.
