Is it ported and compensated? Or are those just slide cuts?

Not to derail or go off on a rant, but why do so many companies add unnecessary slide cuts? I don't want extra holes that just let the dirt in TYVM.

That and aesthetics mostly. I don’t really think fully cutting through the slide provides any additional traction/benefit compared to just normal serrations

Yep and to keep the slide speed correct.  The more efficient or heavier the comp the more you have to cut out of the slide to make the gun run

That’s certainly one of the methods for dealing with compensated pistols. There are a combination of other factors/variables you can adjust to tune (or ruin if done poorly) the reliability of a comped gun

Reciprocating weight, operating spring (recoil spring, mainspring if applicable, etc) weights, and overall energy of the load you’re shooting has been my experience.

The energy that the compensator uses to counteract recoil/muzzle climb is being taken from the energy that’s generally used to fully cycle the action. It’s why a lot of people report that their pistol which was previously 100% reliable on standard pressure 115gr target loads suddenly started having weak ejection or failure to eject problems on the same ammo after adding a compensator. Once the comp robs a portion of the energy from the ammo to counteract recoil, the overall system no longer has enough energy to overcome the reciprocating weight and/or operating springs in order to fully cycle the action and put a new round in the chamber. Reduce the reciprocating weight, lighten the operating springs, and/or use loads that have a higher overall energy level and those problems will go away.

With the XC, Staccato uses slide milling cuts and a much lighter recoil spring (7 lbs if my memory is correct) to account for the energy loss due to the compensator and still keep the pistol as reliable as possible with the widest variety of factory ammunition

A comp is not stealing energy. It is requiring more energy for the overall system to reliably cycle.

Adding a comp does not reduce the amount of rearward pressure that the gasses apply in the breach face.

Correct, it doesn't reduce the rearward pressure, it counteracts it.  But the effect is still the same, you need to lighten your spring pressure and/or your reciprocating mass, and/or increase the pressure of your ammo.

It counteracts it in terms of the entire system, but it doesn't reduce the force going into the slide (ie cycling). A barrel with a mounted comp is going to require more energy to move, hence the need for more energy. The comp isn't stealing any of the force that would be used for cycling and putting it towards recoil or muzzle flip reduction though.

Even an integral comp that adds no weight will require more force.  You're taking some of the wasted force that was being expelled as muzzle blast and redirecting it to apply forward pressure on the reciprocating mass, or in the case of fixed barrel firearms you're pushing the entire firearm forward against recoil.  On a recoil operated firearm, this is going to require either an increase in force or a decrease in reciprocating mass or a decrease in opposing pressure.  

The minuscule amount of weight added by a muzzle mounted comp isn't enough to degrade reliability significantly.  Browning style recoil handguns are generally tolerant of roughly 3-4 ounces being added to the reciprocating mass.  Dropping locking block style actions, usually up to about 8 ounces.

Yes, it does. The compensator works at peak efficiency when the bullet hasn’t exited or “uncorked” from the end of the compensator, at which point the expanding gases that would otherwise be applying pressure to the breach face escape upward from the expansion ports, which is what provides the force to counteract recoil and muzzle flip.

Which is why you need to either add more input force using hotter ammo or reduce the amount of force required to cycle the slide by reducing the reciprocating mass or the action spring weights

A compensator is typically added on at the end of a barrel, some are cut into the existing barrel, but thats not the typical application... so any gasses escaping upwards through the comp would already have reached a point where they are escaping in all directions and would have no impact on the rearward force the gasses are applying.

Then why in practice do people run into problems with not having enough energy after adding a thread-on compensator to the end of a barrel? Why do you need to add more energy if the compensator isn’t diverting/leaching/stealing some of the energy that was already present?

You can run weights up to 3-4 ounces on the barrel without affecting reliability.

I've never heard of someone running barrel weights... not saying it's not done, but I know nothing about it. It could also be the downward force at the end of the barrel is making it harder to break lockup, thus requiring more rearward force.

Suppressors and old bullseye guns Browning style recoil can take up to 3-4 ounces before affecting reliability.  Dropping locking blocks can take up to around 8.

Close but not quite.  Ports work that way.  Comps are slightly different. Once the gas is in the expansion chamber it is no longer acting on the breech face.  If you were to just let it loose it would be wasted energy.  But once it hits the front wall of the comp it is redirected into pushing forward on the gun, which is why you generally need hotter ammo or a lighter slide/spring.  You're redirecting otherwise wasted energy to counteract the recoil.

Suppressors on handguns also require a piston adapter no?

I've also seen them cause tons of issues, even with the additional back pressure.

You’re right, in this sense I was wrong.

But it’s not the extra weight on the end of the barrel that requires the extra energy

They’re more commonly referred to as sight blocks these days but it’s an old concept:





It’s basically a compensator without ports. An extra chunk of metal stuck on the end of the barrel

Some, but the point being the weight of the compensator isn't as significant a factor as the compensatory affect caused by the gas hitting the face of the comp.
