Tired of how snappy your pistol is? We were too, that’s why we started porting our barrels to unlock its hidden potential. Simply place your order below, mail your slide assembly to us and we’ll get it back to you with more holes than it came with! Check out our FAQ here for more info!
What is barrel porting?
This isn’t anything new, barrel porting has been widely used by both competitive and recreational shooters as early as 1972. It’s really simple, you ventilate pressurized gasses from the top of the barrel which in turn, pushes itself downwards. It’s an extremely efficient way to mitigate recoil, similar to how a turbo charger uses exhaust gasses to spin a turbine; we use some of the pressurized gas to assist with recoil.
Benefits of porting:
Drastic decrease in muzzle rise
No extra pieces or hardware to deal with
Easier to clean and service your pistol
Same holster compatibility
Drawbacks of porting:
Significantly louder
Permanent modification to your slide & barrel
5-10% Muzzle velocity loss (depending on barrel length and ammo)
Slight accuracy loss (increase in groupings at distance)
Great, how do I get mine done?
Please choose your port options below and if you need a window cut on the slide. (If you can visibly see your barrel through the slide, that’s a window!) If you’re wondering if we can port your existing window, please shoot us a message. You will be responsible for shipping your slide and barrel to us. USPS Priority mail is recommended. We’re not responsible for your parts until they’re in our hands. USPS Priority return shipping is included in the price. Once you’ve placed your order, please mail your parts to:

Porting Philosophy
You may have noticed our ports and windows are different sizes across multiple makes and models. We don’t have set parameters since there’s so many variables and measurements we’d have to account for. We simply size up the window and ports in proportion to your slide. Most of our windows are 10×20mm as seen on our Glocks, but for non-conventional or slim slides, we may scale down to 8×16, or go up to 12×24. The ports are usually 5×3 oblongs. We like the shape for both its soft edges and displacement potential, in short, it has the least shredding and most mitigation properties. If you prefer circle ports, let us know.
Placement is also very important to get the most out of your ports. We prefer them to be as far away from the chamber if possible, this is usually right behind the front sight. The reason behind this allows for both adequate barrel pressure and sufficient rifling engagement while maximizing the mechanical fulcrum of the barrel for the best recoil mitigation. In cases where the barrel is too short, or if the factory window is too close to the chamber, we’d still see a significant drop in recoil, it’d just be not as optimal.
Not sure what to pick?
Sub-compacts (i.e, Glock 43, Sig P365) Double port right at the very end will eliminate most of the snappiness with a very sharp vent right as the bullet leaves the barrel.
Compacts (i.e, Glock 19, RXM, P365XL, Fuse) Double port if you plan on carrying it. A standard straight 4 will give you a smooth and reliable shooting experience.
Standard (i.e, Glock 17, M&P 9 2.0, PDP) Straight 4 or 6 would both work great.
Jumbo (i.e Glock 34, 17L, PDP Pro, M&P 9 5”) Standard Straight 6 is the way to go for the most linear recoil impulse.
DISCLAIMERS
Proceeding with your order implies you agree to this disclaimer!
Please note that this is a permanent modification to your firearm parts and while we have plenty of happy customers, there are no warranties or guarantees, expressed or implied. There is always a chance of injury with anything firearms related. Please wear protective equipment at all times while on the range.
There is a chance you may need to tune your firearm’s recoil spring and/or ammo to cycle reliably. We test our ports on Glock pistols with 124gr 9mm ammunition with the factory spring. Other makes and models may have different slide and spring weights and variances that would require adjustment.
In the event of a defect during production, we’ll reach out to remedy the situation. 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. We like to refer to this as, “character” If you prefer machine cut ports, please reach out to your local machinist!
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. Some Cerakote finishes may discolor from the heat. Unfinished stainless steel barrels will show discoloration as well.
