I have a question that I've never seen addressed. Regarding a CO2 gun, does that fact that the CO2 is in the form of a liquid add weight to the gun? (liquid is more dense than air) Also, since it is liquid, does it 'slosh around' a little in the cylinder when you’re trying to hold it steady? My reasons for these question? I'm trying to decide between Air and CO2. I see advantages to both but air seems to be popular right now. Because it's relatively new or.... Thanks for any replys.

Absent any comments from real experts, I will offer mine. (Where are you, John Bickar?)
:Regarding a CO2 gun, does that fact that the CO2 is in the form of a liquid add weight to the gun?
Yes, it gets a little heavier. So does the air tank, though. I don't know what the difference is but in either case it is not much.
:does it 'slosh around' a little in the cylinder
Not noticeably, even when you just hold the tank and shake it. A non-issue when shooting, certainly.
:I see advantages to both but air seems to be popular right now. Because it's relatively new or...
The technical advantages of air seem to me (a relatively new shooter but with an engineering/physics background) at the margin and probably applicable only to very top line shooters. The CO2 guns, being unpopular, are available at quite a saving. Also, they are slightly safer since the pressures are lower.
I have two CO2 guns, an LP1 and an LP5, both bought from Scott at very attractive prices because they have become "unpopular." Until I can consistently shoot groups of two pellet diameters or less I am not going to worry about upgrading to air.
YMMV,
Geo.

Air is much better. But humidity (of the air) can be a problem (pumping humidity inside the pistol). An experiment was performed, by an Italian firm, with air and CO2 mixed. Results were negative. The dynamics (i.e. acceleration inside the barrel) of the air was different from the dynamics of CO2.

I have never used CO2 myself, but I see those who have used it are now using compressed air instead. I have seen no problems using compressed air. With the new pumps, the filling problem (having to use a scuba-tank) is also solved, making it easier to fill, especially when travelling. I also hear that there are problems with the accuracy of CO2-pistols due to changes in temperature.
I will advice you to go for the compressed air. There is a reason why "everybody" is using it, not only that it is popular right now.

I find there are some things wrong with this, particularly the statement that CA is more accurate because it has faster velocity going out the barrel,. both gases can easily be adjusted to the same exact pellet speed.
I have said before there are advantages both ways depending on your filling needs, and shooting environment. shooting below 50 or above 100 degrees can possibly be a problem with CO2, and if you live an area not convenient to get air or CO2 , then CA with a pump is the way to go . As far as performance goes, the temp/accuracy thing is basically bogus, unless you are breaking 570s, then you might possibly be able to tell the difference. My opinion, if you don't have to use the pump because of your location, get CO2, its cheaper short term, cheaper long term, is 100% maintainable by the user and is safer.
