I am new to the TT33. I was attempting to disassemble it, and the whole safety mechanism (bar) fell out of it and is broke! Can the gun function safely without this? If so, I will TIG weld it and park. I need to know if this is a safety issue. (no pun intended.) Did they alter the gun in a way as to make it unsafe without the safety? I know that the safety is an add on to importation rules.
