Glock Barrel & Slide Porting

We offer precision barrel and slide porting for Glocks. Our porting is angled to match the factory look, giving your pistol a clean, OEM-style finish. 

Compatable with full size and compact models.

THIS IS OUR STANDARD PORTING SERVICE. CUSTOM PORTING OPTIONS ARE AVAILABLE.

Performance Benefits:

• Reduces felt recoil.
• Allows quicker follow-up shots.
• Tested with a wide range of factory ammunition (115gr, 124gr, 147gr, target, and defense loads).
• Reliable cycling with all standard factory ammo tested.

Notes on Ammunition:
Very light competition loads may experience cycling issues. This is common across many pistols, and additional modifications may be required if you plan to run such ammo.

Finish & Edges:

• Ports are cut with coolant it’s a CNC thing.
• All edges are left sharp, with only a light stoning inside the barrel ports.
• We do not offer coating or plating after porting - customers can apply their own finish if desired.
• Besides, carbon buildup is the finish any real shooter desires.

**Disclaimer: Barrel and slide porting modifies factory operation. Some models may experience increased carbon buildup due to redirected gases. Performance and results vary by model and ammunition.**

What to Send:

• Only your barrel and disassembled slide (we do not disassemble slides)
• If you send your slide assembled, you’ll need to clean it upon return, so we recommend disassembling it beforehand to save time
• Please provide your phone number in case we have any questions.
