After being quenched and tempered, this small firing pin seems to have been reborn, exhibiting a deep metallic luster and a deadly cold and hard texture.
"This...is that all?" Old Sun's voice was a little dry.
"not yet."
Su Tang picked up the firing pin, returned to the lathe, replaced it with the finest wool polishing wheel, and began the final fine polishing of the firing pin.
She was polishing not just any part, but the slightly curved concave tail and the needle tip responsible for striking the primer, which she had redesigned.
Under her manipulation, those two areas quickly became so smooth and shiny they looked like mirrors.
Old Sun leaned closer to take a look and was completely stunned.
He'd repaired guns his whole life, and he'd never seen a part machined so...perfectly!
That's no longer an industrial product; it's a work of art!
"Girl...you..."
"Master Sun, let's find a gun to try it out." Su Tang handed him the finished product.
Old Sun took it with trembling hands; the tiny firing pin looked exceptionally delicate in his calloused palm. He strode to the workbench, picked up a disassembled Type 54 pistol, and skillfully installed the new firing pin.
Assembly complete.
He pulled the slide and loaded the gun.
"Click".
The sound was crisp and incredibly smooth.
Instead of loading live ammunition, he found a used empty cartridge case, put it into the magazine, and chambered a round again.
He took a deep breath, aimed at the sandbox in the corner, and pulled the trigger.
"Smack!"
A crisp, short firing sound rang out.
This sound is completely different from the slightly muffled firing sound of a regular Type 54 pistol!
Old Sun was startled and quickly removed the spent cartridge.
He took the empty cartridge case up to the light, put on his reading glasses, and examined it carefully—
Right in the center of the cartridge primer was a perfectly round and regular dent, neither too big nor too small, neither too deep nor too shallow!
Perfect firing marks!
He had repaired guns his whole life and handled thousands of guns, but he had never seen such a perfect firing mark!
This means that the force of each shot is exactly right, applied evenly to the most effective position!
This means higher reliability! Lower failure rate! And even... higher accuracy!
Old Sun held the small bullet casing, his hands trembling like leaves falling in the autumn wind.
He looked up at the calm-looking girl in front of him, and his eyes instantly reddened. His voice was filled with an incredulous excitement and awe.
"You are a peerless hero! A peerless hero indeed!"
"Su Meizi! With your skills, it's a waste to keep you in such a small place! You should go to the military factory in Beijing! Go to the country's top weapons research institute! Do you know what your skills mean? They can take our country's light weapons level a giant leap forward!"
Faced with Old Man Sun's almost out-of-control agitation, Su Tang's reaction was as calm as a deep pool of water.
She took the perfect firing pin back from Old Sun's hand, examined it under the light, and then interrupted Old Sun's excitement.
“Master Sun, national affairs are too far away. I just want to make a handy weapon.”
Su Tang carefully put away the firing pin, turned to Chen Xiaocao who was still standing there in a daze, and said, "Let's go, the work is done, it's time to go back."
