Which pressure gauge to use?

[mr doo doo]

On my pump and pistol mag, i use two types of air: regular CO2 tank and 12 grams. what is a good PSI range on a gauge to use for my mag? up to 600 psi or 1200 psi? unless it is something else....?

Isn't CO2's output like 700ish? If so, the 600psi guage might not work. I'm not too sure.

Off the top of my head, I believe that CO2 liquifies (which is what a CA tank is full of) at around 900psi? I could be mistaken as it has been years since I actually sat in a chemistry class. Those 600psi (and lower) guages are for post regulated line pressures, and most likely not for a mag as my mini likes it somewhere around 700 and above

my gauge says around 900 when i use co2

cool, so i guess 1200 psi gauge it is! when i ran CO2 on my spyder, it would go to 500 psi on a 1200 psi gauge, but that was a spyder...

yeah... use a 1200 psi gague.

But... um... what's the point? The pressure inside a CO2 tank isn't like the pressure inside an HPA tank. You won't be able to tell how much air you have left by using a gague. By the time it registers a drop in pressure, you'll be out of air.

wanted to use one for my pump mag since it will run on 12 grams, and i never can tell when i'll be out. so there isnt a point of using one when im using CO2?
