I'm probably going to eventually get one or two for my WE P14 (same mag) from redwolf through airsoftparts.

Unfortunately, that mag is currently out of stock.

Well crunchmeister's answer pretty much spells it, best to answer if you actually have used a CO2 with a WE Hi-capa or other CO2 guns (Though won't help much) if not then you might just be leading the questioner on a wild goose chase.

As for long term reliability you can only speculate

very excited, getting guns by saturday and the mags..well we still neeed to order them...but reviews of guns will be up asap with videos.!!

I've used a WE Hicappa 4.3 with both propane and CO2.
Velocity: according to my "how hard it sticks to my Crossman gel target" test, the CO2 mag did not result in much of a velocity increase... it was not shooting as hot as the 317 FPS Luger that I also used with the target.
Rounds per cartridge: at room temperature, I was averaging between 85 - 93 shots per 12 gram powerlet.
Cold weather performance: much to my suprise, this really sucked. Of course, at the temp. that I was shooting at ( -3 to - 5 C? Not sure, it was near the end of October) my pellet pistol did not perform much better. I suspect that the GBB aspect of the airsoft pistol caused the problem, as I have read that otheres have had good luck with CO2 pistols in cold temps. (NGBB, I'm guessing). In fact, after about five rounds of rapid fire on one fresh cartridge it died... when I popped the cartridge out of the mag, I heard something rattling around inside it. Turned it upside down... little white pellet stuck in the opening of the cartridge. I watched it sublimate.... dry ice!!

I think these mags would be great for folks who put a lot of rounds thru their pistols in the summer. All one needs carry is spare BB's, and possibly an extra cartridge or two in one's pocket. With two mags, one could fire over 150 rounds without having to change a cartridge!

(As always, individual mags and guns may vary.)

yes and will rember their is a lot of vairents that make co2 redy guns and non co2 vs of the same gun for instance kjw makes sig co2 redy and m9 redy ones and non co2 vs of the same gun. so rember if using them make shure if its co2 redy and its safte to because all of the guns have diffrently designed blowback chambers and specific parts to lower the incresed wear the parts will endure beacuse the power of c02 is stronger.

uncompany also has them... but Ehobby seems to be the cheapest...

got the guns....got the c02 mags...

All Im gonna say is that the kick is insane compared to green gas.

review of CO2 mag and little cool upgrades to come with picS!!

Great! Glad to hear it, good to see the WE's being put to good use

In other words stay tuned...:D

I have a 50rd hi-capa mag and yeh the pick is ridiculous, I have a WE HIcapa and WE 1911, I swapped the slides and ran propane with it and it feels like a nailgun or something!

does that mean it's good or bad?
