safety removal

Hey so i just got a used condor. I try playing around with it 2 times. Both times i couldnt disengage the safety. I try pushing it forward but it was very hard. It was so hard i couldnt do it with my finger so i got something to push it with (it felt like it was going to break) and then the gun fired. This happen both times. Many people told me the safety sucks and so on.

I try looking for a DIY on how to remove the safety and could not find one.

If anyone has a link to one thats step by step that would be nice.

THANK YOU!
