and I am looking for one holster as shown in the Ad.
FWIW, bought a Mauser P38 off an internet auction several years ago for around $300. Auction had around 6 P38s to sell. Mine sold for at least $100-150 less than others, due to someone pinging the metal heavily on front of the grip. Regardless of the pinging, overall the pistol was in good condition and shoots well.
