Bought a new python couple days ago and just noticed there's a very tiny hairline (about 1/6 inch) on the top of its inner frame right behind the cylinder, running from its outer edge to inner edge. Can confirm it's not the seam cuz the shape is quite irregular. Only noticeable under direct light from a specific angle. Initially I thought it was some fiber dust from my clothes but come to realize it's something carved on the metal as I can feel the unevenness with my nail. Couldn't tell whether it's a concave or convex crack. How much trouble am I in with this revolver? Been shooting it fine with 100 rounds so far.
