Definitely Tig for that,and be prepared to clean up the firing pin hole a bit. I have done them with the arc using a steady hand, the smallest rods, medium amps and dot welding with a water quench between each dot (to avoid heating the bolt head and destroying the temper,) followed by a lot of hand finishing.
