A picture would help if it was clear enough.
If the gun is going into battery without help and running ok, probably nothing to worry about.
My K40 in it's early day started peening and I had to occasionally tap the back of the slide with my hand to drive it into battery.
Kahr replaced the slide and barrel and it's not had an issue since.
