I had a p7m13The squeeze cockers H&K were P7PT8, P7M13, P7K3, P7M10 and the P7M7. They are considered by many to be the best pistol ever made. They bring a premium price because of the quality and rarity. I think they went out of production in 1979. They had several unique features that some were copied by newer manufactures and some never duplicated.
One of those guns you should never sell
