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!

Benefits of porting:

• No extra hardware to deal with

• Easy to service and swap barrels

• Same holster compatibility

• Drastic decrease in muzzle rise

Drawbacks of porting:

• Significantly louder to the shooter

• Permanent modification to your slide & barrel

• 5-10% Muzzle velocity loss

• Slight accuracy loss

Please choose your port options below and if you need a window cut on the slide. For slides with pre-cut windows, please message us. 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. Return shipping is included in the price.

Porting Recommendations

Super Size - 1.5-2x the port size for even more aggressive recoil reduction.

Sub-compacts (i.e, Glock 43, Sig P365) Chunk or 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) Super Sized Straight 4 or a Straight 6. Super sized 6’s work out of a Glock 17 with the stock spring and 124gr.

Jumbo (i.e Glock 34, 17L, PDP Pro, M&P 9 5”) Standard Straight 6 is the way to go. Super Sized Straight 6 if you’re comfortable tuning the recoil spring.

DISCLAIMERS

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 are 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 with 124gr 9mm ammunition and unless expressly stated, all of our firearms operated with the factory spring in each respective model.

In the event we mess up your parts, 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.
