I remember reading a gritty black and white comic strip in Dutch in the (probably early) 1990s featuring a man using a gun to shoot himself in the head, but ending up cussing as the bullet got stuck in the metal part on the right side of his head.

I thought it might be [Mean Machine](http://www.2000ad.org/?zone=thrill&page=profiles&choice=MEANMAC) but he doesn't look very capable of using a gun with his right arm.
