No way to miss those cracks and I don't believe they could have happened in shipping.The cracks show the same wear as the rest of the wood and are probably very old.They should pay return shipping but the FFL is what I would call your own hook. Some FFL's want fifty bucks and some twenty five but I've never paid any cause a hang around shop that knows you as a good customer will at least all I know, do it for free to keep you comming back.Also maybe the gun went back to a more humid climate and all the metal swelled up makeing it tight again.
