PMags, Glock Frames, and Grips](https://go.salasers.com/blog/can-a-fiber-laser-engrave-polymer-pmags-glock-frames-and-grips) Oct 7, 2026, 3:20:37 PM **Short answer:** Yes. A fiber laser can engrave most polymers used on firearms, including PMags, Glock and Sig frames, and many aftermarket grips. The key is controlling heat: polymer melts and bubbles if you hit it like steel. Our standard Edge 50W marking presets for Glock frames, Sig frames, and PMags each run a single pass at 24 to 42% power. Test on a scrap or hidden spot first, and run fume extraction every time. Below are our actual starting presets and how to get clean, consistent marks on the polymer parts gun shops see most.

It handles serial numbers, deep engraving on steel and aluminum, coated parts, and even color marking on stainless steel and titanium. In our testing, it also has a longer focal range, which makes curved and uneven parts more forgiving. A MOPA makes sense if you need the widest possible range of colors, deep-black marks on anodized aluminum, or a lot of polymer work, and those jobs are a real part of your business.

ATF .003" Depth on 30W, 50W & 100W](https://go.salasers.com/blog/how-deep-can-a-fiber-laser-engrave-atf-.003-depth-tested-on-30w-50w-100w) Oct 7, 2026, 2:15:28 PM **Short answer:** Yes. A properly set-up fiber laser, including a 30W machine, can engrave serial numbers to the ATF's .003" minimum depth on steel and aluminum. Wattage changes *how fast* you get there, not *whether* you can. In our shop, an Edge 30W reaches .003" on a 1/16"-tall serial number in 20 passes, about 2 minutes. Below is what the rule requires, how time compares across wattages, and the settings and measuring habits that keep your marks compliant.
