Machine the sides of the slide for cocking serrations, or porting.
Slides will need refinishing after milling.
Front Serrations options:
Through the roll marks– The roll marks on the left side of the slide (Glock <model #> and Austria) are cut through to add the serrations on the front side of the slide. There may be fragments or parts of the numbers/letters left behind that may be visible.
Around the roll marks– The serrations are added around the roll marks leaving all the letters and numbers intact.
Through the roll marks, remove remnants– The serrations are cut through the roll marks, and the remnants of the letters/numbers that were left behind are removed by machining the left serrations on the side of the slide only.
