1859-1863 Sharps Main Spring

*A Note on Installing Sharps Main Springs: Some care must be taken when installing Sharps main springs as it is easy to destroy the spring if improper tools/techniques are used. It is crucial to only compress the main body of the spring when installing in a lock. This should be done with a main spring vice, but a Vice Grip can be used as well. It is absolutely vital to avoid any compression of the sear limb as it will over stress it and render the entire spring useless. We will not accept returns/exchanges on springs that were damaged as a result of improper installation.
