Abstract
In some embodiments, a golf club head has a body with a front section, a first restrictor of a restrictor mechanism coupled to a first portion of the body, and a weight having a first end coupled to the restrictor mechanism and to the body. The first restrictor has a first stiffness and is non-integral with the weight. Responsive to impact at a first zone of the front section, the first restrictor and the first end of the weight react towards each other, and the first stiffness can resist a deformation of the first restrictor by the first end of the weight. Responsive to impact at a second zone of the front section, the first restrictor and the first end of the weight react away from each other such that the first stiffness is substantially non-involved with first end of the weight. Other examples and related methods are also described herein.
