Malfunction

What ammo did this occur with?
Soft primer slam fires?
If the disconnector is timed correctly you can eliminate it from the equation.
Possible that a piece of trash got into the firing pin channel and stuck the firing pin forward. I have seen that happen before but ifsofactso it is odd that it would be a repetitive problem.

Depending on your trigger weight, how you were holding the weapon... maybe you accidentally bump fired the thing.

I'm not an expert by any far cry, but it might be worth looking into. There's some information on the internet about it.

It's happened to me once, but then again she told me not to worry, it happens to all guys at least once.
