I bought an FIE Titan II in 32acp that has two issues that should not be difficult to fix. The first issue is disassembly, I can not get the slide off the frame. I do have the instruction manual via internet but I can not lift off the slide as it slides back. Trigger safety is on fire as per instruction and magazine is removed. Instructions are simple enough but, it will not release. The second issue: the firing pin safety does not work and seems to have a busted spring. I can not replace the spring until I get the slide off. Are these two issues related? Need help! Appreciate your thoughts.
