Argov Precision - Firearms Milling & Porting

Don't see what you're after? Reach out so we can get you sorted.

Our current lead time is 1–2 weeks of shop time. The clock starts the day your part is received at our shop and ends when our work is finished — it does not include shipping in either direction. This is an average, not a guarantee; depending on our workload at the time it can run a bit faster or slower.

Let's talk about porting.

What porting does

Porting allows gas to be pushed upward at a high rate of speed, pushing the muzzle back down for faster follow-up shots.

Every shot produces a torque problem. The bore sits above your hand, so the force driving the bullet forward also rotates the gun around your grip. The muzzle climbs. You bring it back down. You do it again.

Ports interrupt that. Openings cut through the top of the barrel, and through the slide above them, let a portion of the propellant gas escape upward while the bullet is still traveling down the bore. That escaping gas produces thrust in the opposite direction — downward, on the front of the gun — at exactly the moment the muzzle would otherwise be rising.

The idea is not new. Gunsmiths have been porting guns to fight recoil for decades, and the principle is well documented going back to the 1980s. Porting has since become a common offering from firearm manufacturers themselves, showing up as a factory option on more and more production pistols.

The problem is that not all manufacturers are created equally. Many of them under-port the firearm, stopping well short of what a proper port setup is truly capable of. That is where we come in. We take ported and non-ported guns alike and bring them to the next level, squeezing as much out of the setup as we can — with reliability and function in mind.

What we've seen

The point is, it actually works.

In our own testing, the porting we have done has helped across the board — less muzzle rise, less of that snappy recoil, and less abuse taken by your hand over a long session. That is a feel thing, and we will call it what it is: this is what we have experienced on our bench and what our customers report back to us. The point we are making is that it works.

What you do need to be aware of is barrel length. A longer barrel keeps the bullet traveling under pressure for more time before it exits, which is how it builds velocity — FPS, or feet per second. A shorter barrel gives the bullet less time to reach its full potential to begin with.

That is why longer barrels typically allow for more ports. Most customers running a longer barrel choose a higher port count, knowing the velocity they give up costs them less on that platform. Shorter guns are limited two ways: by the space available to place holes at all, and by our own call to prevent excessive FPS loss on a barrel that does not have velocity to spare.

You will feel an improvement either way. On a shorter gun it simply will not be as significant as it is on a longer-barreled firearm — but make no mistake, porting makes a worthwhile difference on both. Short or long, you are getting a gun that shoots flatter and comes back on target faster than it did before.

What you'll notice

Where a ported gun earns its keep.

01

Less muzzle rise

The front of the gun stays down through the shot cycle. Less travel off target means less work to get back on it, and less correction creeping into your grip over a long string.

02

Faster follow-up shots

Sights settle sooner. That recovery window between shots is where split times are won or lost, and porting shortens it without asking anything more of you.

03

Easier to keep the dot in the window

A flatter gun makes it easier to keep the dot tracking inside the glass rather than climbing over the top edge. How much easier comes down to your pistol, your load and your grip.

04

Your holster still fits

Porting adds no length and no weight out front. Carry position, balance, and every holster you already own stay exactly as they were.

05

Softens a snappy gun

Light, compact pistols deliver an abrupt impulse relative to their size, and hotter defensive loads sharpen it further. Venting gas upward smooths that impulse into something more predictable to shoot and easier to stay ahead of.

06

Nothing to come loose

No device threaded onto the muzzle, no extra parts, no torque spec to check. The work is integral to the slide and barrel — permanent, and there is nothing to back off under recoil.

Porting vs. a compensator

Two ways to solve the same problem.

Both vent gas to fight muzzle rise, and compensators do it well — this is not a knock on them. The real difference is what each one does to the outside of your pistol.

Ported slide & barrel

  • Adds zero length and zero weight to the front of the gun
  • Works with the holsters you already have
  • No threaded barrel required
  • Integral to the parts — nothing to loosen or lose

Threaded-on compensator

  • Typically adds one to two inches and several ounces out front
  • Often needs a holster that clears the device
  • Requires a threaded barrel, which some states restrict
  • Comes off for cleaning, and can shift if not torqued properly

In our own testing, a proper port setup will aid in more recoil reduction than a compensator alone. That is our experience rather than a universal rule — and if you are running a compensator with inline ports behind it, you are simply sweetening the pie.

How it works

Three steps, start to finish.

STEP 01

Configure and order

Pick your service, choose your port count and options, and pay online. The price updates as you go, so there are no surprises at checkout.

STEP 02

Ship us the part

Send the stripped slide and barrel — never a complete firearm. We are not an FFL and cannot receive one. Read the shipping instructions before you pack.

STEP 03

We machine and return

Typical turnaround is one to two weeks of shop time, counted from the day your part is received here to the day our work is finished. Shipping time is on top of that. Return shipping is included with your purchase, and tracking is sent to your email.
