H&K Barrel & Slide Porting

We offer precision barrel and slide porting for VP9s. 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.
