a weight mount disposed on at least one of the sole, the crown, and the skirt, wherein the weight mount defines a perimeter wall, wherein a portion of the perimeter wall defines an undercut having an undercut depth R u ; and

a weight member that includes a weight body defining a side wall and a spring feature, wherein at least a portion of the spring feature is movably coupled to the weight body so that it is movable between a first configuration and a second configuration, wherein in the first configuration a portion of the spring feature extends outward from a side wall of the weight body by a first distance R 1 , wherein in the second configuration a portion of the spring feature extends outward from a side wall of the weight body by a second distance R 2 ,

wherein the undercut depth R u is less than the first distance R 1 and greater than the second distance R 2 so that the spring feature abuts the undercut of the perimeter wall of the weight mount, wherein the spring feature is a cantilevered arm, wherein the cantilevered arm includes a fixed end and a cantilevered end, and the fixed end is coupled to the weight body, wherein the weight body includes a diametric bore that receives a portion of the cantilevered arm and the weight body includes a slot that intersects the diametric bore so that at least a portion of the cantilevered arm is exposed when the weight member is installed in a weight mount, and wherein the spring feature is at least partially flexed by the abutment of the spring feature with the perimeter wall when the weight member is installed in the weight mount.

9. The golf club head of claim 8 , wherein the cantilevered arm is constructed as a separate component and mechanically coupled to the weight body.

10. The golf club head of claim 8 , wherein the cantilevered arm is formed by a slot cut in the sidewall of a tubular member.

11. The golf club head of claim 10 , wherein the weight body is a cylindrical member having a first portion having a first outer diameter and a second portion having a second outer diameter, wherein the first outer diameter is smaller than the second outer diameter, wherein the tubular member is coupled to the weight body on the first portion.

12. The golf club head of claim 8 , wherein the first distance R 1 is between about 1.0 mm and about 4.0 mm, and wherein the second distance R 2 is less than 1.0 mm.

13. A golf club head including a weight member, comprising:

a club head body having a hollow construction defined by a face defining a ball-striking surface, a sole, a crown, and a skirt, wherein the sole extends aftward from a lower edge of the face, wherein the crown extends aftward from an upper edge of the face, and wherein the skirt extends between the sole and the crown around a perimeter of the body;

a weight mount disposed on at least one of the sole, the crown, and the skirt, wherein the weight mount defines a perimeter wall, wherein a portion of the perimeter wall defines an undercut having an undercut depth R u ; and

a weight member that includes a weight body defining a side wall and a spring feature, wherein at least a portion the spring feature is movably coupled to the weight body so that it is movable between a first configuration and a second configuration, wherein in the first configuration a portion of the spring feature extends outward from a side wall of the weight body by a first distance R 1 , wherein in the second configuration a portion of the spring feature extends outward from a side wall of the weight body by a second distance R 2 ,
