Cayugad , When you are looking at the right side of the trigger you should have a pin and c-clip on the lower right that hold's it down and one in the upper left that goes in the slot for fire or safty. There should be a dimple kind of to the right of the slot (in the middle) that should have a pointed pin and spring that goes inside of houseing and will stick out the other side a little when you switch from safty to fire.
