Small frame crack

On the P380 i have a small hairline crack on the frame of the gun (about 1/8 inch). Its located on the frame directly in front of the half moon part of the trigger bar. Its cracked along the thin part of the frame (the thin part hollowed out to give the trigger bar room to move back and forth)

It runs from the very bottom of the rail to where the rough grit of the grip starts at the top of frame, like i said its only about 1/8 inch.

I haven't taken it to the range yet as I just sat down to clean it before I went when i noticed it. Anything to be concerned about? Should i shoot it and see how it runs?

I wanted to take a picture but the camera wouldn't pick it up.
