If you want your hammer to do something when you pull the trigger you'd better have a hammer spring. These guys see a lot of use and should be considered a wear item every few thousand rounds. These are standard rate springs and are plenty strong enough to set off a commercial or hard military primer so long as it is installed in the correct orientation.

Installation notes: There is a right way up to mount these springs. The pushing legs of this torsion spring need to be on the same side as the hammer strike face.
