The only one that says green gas 
note I have also go the 13a gas as well ..........
I wouldn't make a habit of using green gas in a pistol with a plastic slide. Best compromise is Ultra gas, which falls in between green (high power) and 134a (lower power).
When I want your opinion - I'll tell you what it is!
Ok i will buy the Abbey ultra one then.If its good.
Cheers.

You probably know this already, but the gas that's recommended for that pistol is the 13a - I have one myself - I take it you're talking about the Maruzen? - 
Gas choice for pistols. Now there's a topic that can be debated for ages.
Ok, the short version.
1: All ASGK/JASG marked Japanese manufactured pistols are designed to run on 134a. In fact a lot of the UK retailers will specify use of 134a under their warranty terms.
2: The gas you should use, depends on the weather.
3: Using a higher pressure gas will drastically increase the chance of causing damage to your pistol (particularly slides cracking)
When it comes to temperature, in the middle of the summer when its nice and warm (fat chance of that this year!) use 134a. Spring and Autumn, use Abbey Predator, in Winter, you can get away with green gas (bit of a misnomer - "old skool" green gas was R22, 95% of "green gas" now is actually propane). I would HEAVILY recommend not using green in Tanaka Lugers or Browning HP's and only cold days for use with P38's.
Of course, if you have a metal slide fitted (yes, they *do* do full metal kits for the Maruzen P38 from Zeke - about 400 quid, last time i checked) then you can pretty much get away with green gas all year round.
When we were a Kingdom it was run by a King
When we were an Empire it was run by an Empress
Now we're a country we're run by a..........
Ok i kinda understand about gas now 
But would the Abbey ultra be fine i brought some last night.

I use 134a in my Marui Colt 1911 and works fine, the "power obsessed" in airsoft always go on at me for using "Marui crap" and not bothering to improve them but if gun its target its all good.
