More holes in your barrel = more holes on target. This service is only for Glock and aftermarket Glock-compatible slides at the moment, for non Glock slides, please fill out the form on our Laser Engraving page.
Please choose your port options, if you need a window cut and finally, your generation and model. Window cuts are an extra $50 and the Straight 6 is an extra $25. You will be responsible for shipping your parts to us. USPS Priority mail is recommended, but you’re free to select whichever carrier you prefer. We’re not responsible for your parts until they’re in our hands. Return shipping is included in the price.

*DISCLAIMERS*
Barrel porting offers significant muzzle rise reduction at the expense of muzzle velocity and accuracy. Please note that this is a permanent modification to your firearm parts and no warranties or guarantees are implied or offered (other than a “trust me, bro”) In the event of a cutting issue, we’ll reach out to remedy the situation. We test our ports with 124gr 9mm ammunition and unless expressly stated, all of our firearms operated with the factory spring in each respective model.
Please note that we do not currently offer refinishing services at this time. Your cut metal will be blued, which will darken the bright, fresh metal and sealed with oil to prevent corrosion. This is the standard practice in gunsmithing.
Please note that while the laser is very precise, the cut still requires deburring and finishing. Our finishing process is all done by hand which will result in some human imperfections. These can vary from wavy ports, visibly rough cuts, un-centered ports, etc. We try our best to make the cuts look good from an arms-length, but if you’re looking for CNC-like cuts, we kindly ask you support your local machinist.
Port Options:
Single (Big Chunk) - Great for short slides like a Glock 43/48, still effective on longer slides, but you’ll have a much sharper vent towards the end of the cycle. Significant increase in felt concussion and sound, equivalent to a compensated pistol or factory port on a Hellcat Pro or 365 Macro. A good option if you’re running a short frame, or if you need to reduce a lot of muzzle flip.
Double - For short slides like the 43 and 19, but for those who prefer a less volatile big chunk while keeping the small window. Less loud and concussive as the big chunk, but still noticeable. A good option for EDC pistols.
Straight 4 - The most common port, fits 19-34 just fine. Not recommended on the 43 as it’ll ride right up against the chamber if you keep your front sight. This port offers a smooth and controlled vent. As the bullet travels through the barrel, the barrel pressure will release through each port in stages along the length of the barrel. Due to the amount of ports, the bullet’s jacket will inevitably be shaved as it travels past each port, resulting in potential shrapnel and accuracy lost. This option is loud and concussive, but tolerable outdoors. Expect significant flames and sparks. Eye protection is highly recommended.
Straight 6 - Just like the straight 4, but with 2 extra ports. This option yields the best results for rapid fire and return-to-center at the expense of accuracy, shrapnel and port flash. We’ve had no issues running the stock springs & guide rods in our Gen3-5 Glocks with 124gr ammo. As this is most concussive port we offer, the shooter will most probably notice their face and sinuses be affected by the pressure. Eye protection is highly recommended.
