This is not the case with many MSP's. Even the common Crosman 760, 1377 etc.
if you pump more than the recommended strokes you get enough air for a weak second shot.
Or they have a half-cock position where you can fire a dozen or so weak shots from
the recommended 10 pump strokes, even if it wasn't intended to fire that way.
So even with accepted factory MSP's there's no clear line with how the stored air is used.

And with a simple mod, some MSP's can be made to hold air for two good shots.
At some point the forums were calling these ACP's, Air Conserving Pneumatics.

When I presented these facts to an arms officer, and the fact that MSP's could reach PCP pressures
and power levels, his response was along the lines of: that's how the current law is written.
They did not want the complication of power testing airguns for a power limit, so they
simply decided that PCP's as a class are more dangerous and the rest are less dangerous.

Bottom line is, if you can fill from an external air source its a PCP. If you can't it's not.

In a NZ context, especially with regards to NZ firearms laws, I think BC_Clark has summed it up well when he says:

"They did not want the complication of power testing airguns for a power limit, so they
simply decided that PCP's as a class are more dangerous and the rest are less dangerous.

Bottom line is, if you can fill from an external air source its a PCP. If you can't it's not."

If authorities were really serious about controlling air rifles for SAFTEY reasons, then the only logical question they should have asked was "how much FPE does it produce?'.
The only way to differentiate "safe air guns" from "unsafe air guns", is by setting a FPE limit. Simple.
It dosent matter how long or short the gun is, it dosent matter what caliber it is, it dosent matter if its a single shot or milti shot, or what the method of propulsion is.
All that matters is how much kinetic energy it can produce.

I know that dosent answer the original question of "what constitutes a PCP"...
But in its simplest terms, PCP stands for Pre Charged Pneumatic, pneumatic pertains to air OR gas's, so as soon as you load a pressurised co2 cartridge into your co2 powered air gun, you have created a "Pre Charged Pneumatic".
Same with a multi pump.

Walk quietly, but carry a big stick.

To counter any confusion, in New Zealand CO2 Powered air rifles do not require an FAL. These rifles are classified as airguns and are not considered "specially dangerous" unlike pre-charged pneumatic air rifles.
The cartridges or capsules contain liquid CO2 that vaporizes when released. Working pressure is @ 850psi and muzzle power 4 - 8fpe.

The legislation relating to PCP air rifles as it stands specifically refers to pressurised 'air'.  There is no mention of other gases such as CO2.

So we can all agree that Co2 doesn't require a license. I do wonder if a self charging gun like the FX independance would be regarded as needing a license if it had no fill port. I guess you could safely call it a multi pump pneumatic.

Yeah, definitely a PCP as it's supplied with the fill port.  I assume the pump is for top-up rather than to fully pressurise the cylinder.
