F.I.E.: Firearms International Export.
Cheap guns, usually not particularly high quality. Made in Italy, Spain, and a few other places, and imported into the USA.
Titan II: Made by Tanfoglio (Italy). Came in .32 ACP and .380 ACP. Magazine held 12 rounds, in .32 ACP.
Lever behind trigger, left side: Trigger safety. Down = "fire." Up (points forward) = "safe."
Lever on slide, near hammer: Firing-Pin Block safety. Up = "fire" (I think).
It may have a "magazine safety," such that when the magazine has been removed, it won't fire. (But I don't know for sure.)
Turn trigger-safety up to "safe."
Pull slide as far to rear as possible and lift rear end of slide up, off of frame.
Slowly and carefully let slide run forward, until recoil spring is free and slide clears muzzle.
Remove slide and spring.
Reassemble in reverse order.
Slide probably stays open on empty magazine.
Remove magazine, pull slide back just a little, and it will probably then run forward.
The pistol is worth next to nothing, but it would be a good piece to learn on: If you break something, you haven't lost much.
Keep ammunition away from it, and fiddle with it to your heart's content.
