.....emery cloth?! Who said emery cloth??

Thanks and point taken.
I attached a pic of the rear of the frame. It's not the best, but you can get some idea of the contact being made.
I contacted the seller about the toggle/breech issue and a possibly cosmetic (?) crack. The seller has since contacted me and offered to refund my money, shipping, and the cost to ship it back to him.
I just posted about the crack issue on the same gun in the Military P-08 Forum under the title "Is this Crack in the frame "normal"?" @
