Firing pin mark

Postby MJR » Fri Jun 15, 2012 8:56 am

Took my M57 out the other day and when I found some of the brass (in the next county) I found that the primer had the normal dent from the firing pin but also had what l;ooked like a drag mark from the detent halfway out to the edge of the primer. I guess the firing pin is sticking out and not retracting before the case is extracted. I had cleaned the channel so am thinking I need a stronger spring. Wolff only shows springs for the tt33. Any idea where I can get one for this gun ?
