Glock Frame Stipple: Fiber Walkthrough

Custom laser stippling on a Glock 17 frame. Premium firearms personalization; realistic retail $130-180 (after labor and a small scrap-rate buffer for customer-property risk). Total time: ~30-45 minutes (includes disassembly + masking + engrave).

The order

"Stipple grip on my Glock 17, aggressive grip pattern, full grip area covered."

Materials & tools

• Customer's Glock 17 frame (must be disassembled)
• 3M ScotchBlue 2090 painter's tape (for masking), low-tack, no adhesive residue on a customer's polymer frame
• Vector stipple pattern file, common patterns include "shark tooth," "pebble," "scallop." Sources: paid template bundles from firearms-engraving template vendors, or build your own in Illustrator/Inkscape using a tiled pattern brush.
• Frame jig, model-specific cradle that holds the Glock at known position. 3D-printable models are widely shared; verify the jig fits your specific frame generation (Gen 3 / 4 / 5 / 47 differ).
• Stiff nylon brush (post-engrave cleanup)
• Compressed air can

Step 1: receive customer's firearm

1. Customer brings frame in person (don't ship firearms across state lines without FFL).
2. Photograph the frame BEFORE engraving, documents pre-existing wear / damage.
3. Verify: slide is OFF, magazine is OUT, chamber is checked clear, all internals removed (firing pin, extractor, recoil spring assembly).
4. Confirm with customer: stipple area, pattern preference (light pebble / aggressive shark-tooth / scallop), undercut requested?
5. Get customer signature on liability release: "Frame engraved at customer risk."

Step 2: prepare frame

1. Wipe frame with isopropyl alcohol, removes oils.
2. Mask off areas that should NOT be stippled with painter's tape:
   • Magwell opening
   • Takedown pin holes
   • Slide rails
   • Trigger guard interior
   • Top of grip if customer wants only finger areas
3. Press tape firmly so edges don't lift during engraving.

Step 3: mount frame in jig

1. Place model-specific Glock 17 jig on bed.
2. Drop frame into cradle, should sit firmly with grip exposed upward.
3. Verify Z height, note the focal distance for the highest point of the grip.
4. The grip is curved; you'll engrave each "side" or "panel" of the grip in separate passes if focus drift is significant.

Step 4: setup Lightburn (galvo edition)

1. Open the stipple pattern file. Vector pattern (SVG/AI) is the standard approach, set the layer to Fill mode so the laser fires inside each pattern shape. Some users instead use a high-resolution raster halftone image and Lightburn's Threshold image mode; both work, but the vector path gives more predictable, repeatable texture.
2. Position the pattern over the grip area in Lightburn. Mask any non-stipple zones (top of grip, takedown areas) with vector cutouts.
3. Lens choice: 150mm (or longer), the larger depth-of-focus tolerates the grip's curve. Trade-off: longer lens = slightly larger spot size, so very fine pattern detail blurs. For aggressive shark-tooth patterns this is fine; for very fine pebble texture you may prefer 100-110mm and accept doing two grip "panels" with a refocus between them.
4. Settings (starting points, TEST on the magwell first, see Step 5):
   • Speed: 1200-1500 mm/s
   • Power: 30%
   • Frequency: 60 kHz
   • Q-Pulse Width: 120 ns
   • Line interval: 0.10 mm
   • Passes: 1

Step 5: TEST FIRST

This is critical. Polymer melts permanently; bad settings ruin the frame.

1. Test on the inside of the magwell (hidden area).
2. Run a small (15×15mm) stipple test patch.
3. Inspect under loupe: should be FOAMED texture, not GLOSSY MELTED patches.
4. If glossy spots appear: drop power 5%, increase speed by 200 mm/s. Re-test.
5. Once test looks correct, proceed to grip area.

Step 6: run engrave

1. Position over front of grip (or first panel).
2. Frame to verify alignment.
3. Press Start. ~3-5 minutes per grip area depending on size.
4. If multi-panel: rotate frame in jig between sides.
5. Total: 8-15 minutes typical for full grip stipple.

Step 7: post-engrave cleanup

1. Remove frame from jig.
2. Carefully peel painter's tape, removes any bordering smoke.
3. Brush stippled area with stiff nylon brush, clears foamed polymer dust.
4. Compressed air to blow out any remaining particulate from undercuts.
5. Wipe with dry microfiber cloth.

Step 8: final inspection (cosmetic + function)

1. Inspect under daylight LED. Stipple should look uniform texture across the entire grip.
2. Run finger over the grip, should feel grippy, not slick.
3. Check for melted/glossy spots, if any visible, customer-service issue (frame is permanently damaged at melt sites).
4. Function check before release. With the slide and internals reinstalled (or with the customer present during reassembly), verify trigger function on snap caps, slide cycling, magazine seating, and takedown lever operation. Any binding, dragging, or mis-fit indicates frame deformation from heat, do NOT release the firearm to the customer until resolved.
5. Photograph for portfolio (post-cleanup, post-function-check).

Step 9: customer pickup & reassembly

1. Customer comes in person to pick up.
2. Inspect together, show them the stipple texture and the completed function check.
3. Confirm reassembly state per the callout above.
4. Final payment due before release.
5. Provide a small dust-cleanup brush (optional gift) for ongoing maintenance.

Pricing breakdown

Customer-supplied firearms work carries scrap risk that retail pricing should reserve for. The scrap-rate buffer above protects the shop on the rare frame-damage event; without it, one melted frame wipes margin on 5+ successful jobs.

Common pitfalls

• Glossy melted patches = power too high. Permanent damage. Test FIRST in hidden area.
• Inconsistent texture across grip: focus drift on curved surfaces. Use 150mm lens or break into multiple panels.
• Tape lifts during engrave: press firmly before mounting. Use fresh painter's tape.
• Customer expectation vs reality: show them samples first. Some customers want hand-stippled aesthetic; laser is more uniform.
• Customer takes possession of disassembled gun: verify all parts go back with the customer. Don't lose any pins.
