TM HK45 - Gas Options

[JustEggOkay]

Hello my gas blow back wizards,
I've recently purchased a TM HK45 only to discover the enormous amount of conflicting information online to which gas I should use with it. I've recently returned to Airsoft after a 10 year hiatus so excuse the lack of knowledge.

The manufacturer recommends low pressure gas (blue gas or Abbey 144a Predator type gas) due to the plastic slide.

HOWEVER

the next 6 months in the UK are probably gonna be sub 15 degrees give or take, so am I better off using green gas to compensate for the lower temperatures or shall I play it safe and use low pressure gas regardless?

Cheers!

I have an old TM HK45 from back when they were relatively new. I've always run it on green gas and it's showing no issues at all.

Your mileage may, of course, vary.

In sub 18vdegrees all TMs will run fine on green you need the increased pressure to combat ambient temp. Over 18 stick to 144A gas.
