On the right-hand side of the gun, in front of the trigger, is the handle lock, which is a pin with a small projecting lever resting in a horizontal position. Turn this lever upward and backward as far as possible. Withdraw the handle lock. This releases the handle, which then can be removed rearward. The handle contains the mainspring, hammer, sear, sear spring, trigger and trigger spring. To remove the hammer and mainspring from the handle, pull back the trigger, release the sear by pulling the nose down, when the hammer and mainspring will fly out, as the sear holds them in place. 3.
