Heckler & Koch P7. This version is also called the 'PSP', short for 'Polizei Selbstlade Pistole'. This pistol is chambered in 9x19mm.

Unique features are the pivoting front strap which serves as the cocking lever, decocking lever and slide release. The magazine release is the heel type, at the bottom rear of the grip frame. The pistol has a fluted chamber, polygonal rifling and employs a gas-delay blowback operating system.

Gas is tapped from the barrel just in front of the chamber into a tube below the barrel. This gas pushes on a piston attached to the front of the slide. This pressure keeps the slide closed until the bullet has exited the muzzle and pressures have dropped to a safe level. The barrel is fixed to the frame and has no other locking mechanism. Consequently it strips and operates similar to a straight-blowback pistol.

It points very naturally thanks to its 110° grip angle and the felt recoil is a bit less than my other full size 9mm's.
