Huben GK1

I thought the UK GK1s are regulated in order to stay under the UK's pistol power limits.
Yes & no.
The original .25 V1 non regulated was a little bit too close to the UK's power law limit when filled to a full 259 Bar fill, but the .22 was OK.
Huben in Spain then introduced the regulator just to be on the safer side of things.
Saying that, Huben now makes the V3-R which can now shoot well below the UK's limit un regulated.

The only regulated GK1 is through Francisco's shop. It's aftermarket parts and would leave you with a small plenum. The GK1 self-regulates well enough for a pistol.

I have a V1 in .25 and a V3 in .177. The main visual and functional difference is the up vs down on the loading lever. I believe there are even differences within the V3 line. huben3dparts sells a RDS and a pic mount rail that use a pre-drill hole in the top of the receiver - my new 177 V3 does not have that extra threaded hole.
That isn't correct mate.
First of all the non regulated GK1 does not regulate ??
It does shoot very consistently to a certain point, but a regulated airgun/pistol will always perform / do it better.
Huma also make a very good regulator kit.
 
Is the regulated all that much different than the non?
Does the regulated take away much volume in the airtube?
To be fair if you want the GK1 for max power then a regulator isn't the way forward.
But if you don't mind some non crazy yet still decent powers and each shots power to be pretty much identical, then the Huma kit is worth every penny.
Yes possibly you lose a tiny bit of air but the power consistency is amazing.
My Regulator is set to 125Bar (this is probably the lowest you can set it to in order for the gun to index correctly) and in a .25 calibre shooting at:
12fpe = 105 shots.
20fpe = 75 shots
30fpe = 34 shots
All with a power deviation of 1 (if that)

Obviously in Carbine form with a nice scope on it, power consistency is always a bonus and let's be honest, 30fpe is still a massive amount of power.
In the UK the power law for pistols is sub 6fpe
Rifles/Carbines is sub 12fpe

I visit Greece quite often where there are no power restrictions and that is where I shoot mine at 30fpe.

I hope that helps. 👍🏻

Thank you for such a concise answer.
Yes, I’m keeping my v3 .25 non regulated.
I’m extremely happy with its performance like it is.
Good evening.

Well as I'm the UK's Huben warranty repair guy for Huben in Spain, I kinda know my stuff. 🤣
Plus I am also personal friends with Gregor (who invented it) and although Huben asked for his input regarding the production model, they didn't actually take all of his points/recommendations on board.
When you say they were made at the same time are you referring to a specific part? Maybe I missed it but I don’t think you answered @Ezana4CE ’s question.

Thanks for that info. I’ve always been skeptical because the plenum space must be only ~10cc including the volume in the action. I shoot my .22 at 19fpe, so perhaps I should try it.

Meaning the V1, V2 and V3 were all made at the same time.
It's not like each different version was an upgrade to a previous numbered model.
Saying that, the V3 has now got a couple of extra modifications in it from the first V3 that came out.

At that power the regulator would work well for you.
Although the unregulated versions power is quire consistent, the regulated versions power deviation is almost non existent.
