KJW CO2 Magazine for KJW & HFC M9 Series Gas Blowback.

5 Customer Reviews

by William I. on 03/13/2010
"This mag is absolutely great. I use it in my kjw m9 and it gives it a great kick and has great gas usage. I can shoot about 4 1/2 mags before it gets weak. Im going to buy more of these great things and get rid of my green gas while I wait for these to get here.

"Works absolutely great! I had many problems with the green gas powered magazine but since I have had this magazine. I have had no problems. It holds more gas for about 3-4 mags worth, doesn't stick out that much, and has more power/recoil. Highly recommend getting these magazines to replace the green gas ones you may have.

"These are generally great magazines. I'll give it that. I am a CO2 kind of guy so naturally I switched over to these. These are very gas efficient and being a long time CO2 owner I will strongly advise that buy these at your own risk. And by risk I mean that because naturally the CO2 canisters are very high pressure, it will accelerate wear and tear on your internals. Since nobody seems to be throwing that out there I thought I'd be generous. I would give it a couple months before you'll need to start changing parts depending on how often you use the pistol. But if you're willing to follow this road then by all means, buy it! I am a firm CO2 owner and will be for a long time. Great mag, great gas feed, adds "umph" to your shots, hard hitting. I would buy many more of these if I had the pouches to carry them.

Pros:
Great Gas Efficiency
Hard Kick
Hard Hitting
Gives a more "official" feel to your M9

Cons:
Accelerates wear and tear like a mofo
That's really all I could put at the moment.

4/5 in that it'snot perfect but for the most part, reliable

"I own 4 of these magazines. Only 1 held gas. The rest, even in their brand new condition, leaked straight out of the box.

When they hold gas, they work brilliantly, and do feel of good quality construction i've come to expect from KJW

Im always dubious when buying these mags, and often wait till they're marked down in price, due to the high chance of leaking.

"Magazine I got leaked right away, never got a single use out of it.
