Abstract

In a recoil-spring device (100) in a handgun equipped with a breech and a recoil spring (110) in the form of a spiral spring, whose rear end abuts a rear stop member (123) on a recoil spring rod (120) and whose front end is mounted for movement along the recoil-spring rod (120) with contraction of the recoil spring (110), support in an uncomplicated recoil-spring eyelet is achieved in that the front end of the recoil spring (110) abuts, at least indirectly, a rear contact surface (132) of a contact element (131) that is mounted for movement along said contact-spring rod (120), while the front contact surface (133) is in contact with an internal surface of the breech of the handgun.
