ASG 25 Round Magazine for ASG/KJW CZ P-09 Duty Gas Blowback Airsoft Pistol (Type: CO2)

"used it for the C02 version and it worked great.

"These mags work great even though I only bought one aha one I wish I bought my other four here as well; I can tell Evike checked the co2 seal for me too right before they shipped it out because there was no sticker on the bottom and there was a very very very minuscule amount of wear I'm assuming from an Allen key at the bottom of the mag. Thanks Evike for making sure the mag works for me!

"Good alternative to the co2 mag

"It's been very good to me, so far. Easy to load and shoots well.

"Great gas efficiency! I am running this on the CO2 version with no problem.

"I have had zero issues with the 2 magazines I have purchased. They function as advertised.

"I strongly disagree with the review above for these reasons:
-I own 4 of these mags(and the gun) and have no problems
-I get about 3 mags worth of shooting for each cartridge
-great metal quality
-high capacity
-factory made products are all made the same way and its the distributor or shipper's fault if it sucks.
-heavy mags
-strong spring may be a con because it broke the feeding lip(my fault)

Only con if have is:
-base plate falls of sometimes, but you can but extras for cheap

"So these may leak for you. If they do, simply hold some heat to the o ring long enough to get warm, but not burn. Other than that, they are fantastic

"The mags(c02) are pretty good. It's simple to keep them from leaking, assuming there is not a preexisting defect.

1. Put silicon oil in top.of each c02 when inserting. This will help keep the seal lubed.

2. Be sure to tighten just enough to where you hear no gas coming out. Do not over tighten. This will smash the seal down further than necessary.

3. Clean seals and valves after use and apply silicon oil to puncture vale seal, knocker valve and top seal of mag (little square seal where gas comes out.


If you do all these things the mags should last a good bit of time.


My only real complaint is that the loading tab.hasnto be held down manually while loading instead of a locking mechanism. That's why I give it a 4 star.

"I’ve read through the reviews everytime before buying a new mag, I’ve owned probably close to 8 now and I’m ordering 3 more with two new pistols coming in. I’ve noticed that some mags as well as other people pointing out have issues almost immediately after using for the first time but some mags work perfectly for a long time I feel like the people making these should look into issues for either the seal not being made properly or maybe just co2 brands don’t function well with these mags.

From experience just make sure to tighten the mag enough that it won’t leak don’t over tighten it. Be sure to take the co2 out AFTER it’s all been used, don’t attempt to remove if there’s still some left but all the issues aside I love these mags, easy to load with a speed loader and simple to put canisters in. It just takes time and practice and of course several mags to get the hang of them

"Bought two of these mags and they both had the same leak, but I did find a solution.

It's pretty common for Co2 Magazines to leak after a while; especially when installing a new 12g Co2 cartridge. Still, I like using Co2 over green gas so I bought two of these for my ASG CZ P-09 (Great gun btw). It seems after about 8-10 cartridge changes the O-Ring inside the magazine for the tip of any new cartridge doesn't seat right and slowly leaks the gas out, bad right?

Well I found if you take a small square of electrical tape and cover the tip of any new Co2 cartridge before tightening it acts as a great gasket between the two. Some other advise, tighten quickly but Do Not over tighten when installing new cartridges. If you over tighten you will leave and impression in the O-ring in the mag and it will fail early. This may have been what I did wrong but it was amendable with the electrical tape fix.

All in all good mag, nothing else has let me down.

"Great mags, they feed very well after a couple of fills and can shoot a full mag no problem. My only gripes are of two things, one to fill the mag it's annoying to hold down the spring because there is almost nothing to grab on too. And two the bottom is made of cheap plastic that if dropped can break. Out of the four mags i have, two of them on the bottom have broken.

"These mags are very expensive and hard to find. But are durable and quite gas effecient.makes ur co2 gun shootlow for indoors

"Gas efficiency is absolutely insane with these magazines, only con is that when games are over you have to make the choice of removing them early or waiting until your next game to empty them. I don't have a proper estimated but I think one cartridge goes through about 4 full mags, right on par with elite force, and maybe more. Only problem, is that for some reason this makes the P09 dry really fast, and makes it lock up partway with the slide cycle, or make the gun just fully lock back the slide even when the mag is not empty. It's completely fine though, just lube your gun well once that happens if you have a break, and you'll be fine. You can just pull the slide back a bit and it'll rack forward like normal. Just don't ignore it, it's needless wear you can avoid. This gun needs plenty of oil with these mags, so I assure you, DO NOT skimp on it, it'll only backfire. Anyway, these mags were pretty darn great, just avoid overfeeding too much, it may cause this one weird jam that is really hard to fix, and your gun will keep dry-firing while your bb's are not feeding during this jam, and I think I may have needlessly damaged my gun, as this happened while I was using a tracer, and merely assumed it was malfunctioning instead, so learn from my mistakes, and always put in a reasonable amount, as it has plenty f space anyway. Btw, if you are new to airsoft, and don't know much about gas mags, DO NOT put oil the in the feeding/bb containment area of the magazine like it said in the manual of the original gun, it will impair the function of the mag over time, so just don't touch it. (I didn't do this, I just knew already)

Final Note- All in all, this magazine is really nice, and actually better than most, including the wider bottom for easier bb access, but not a full 5 star due to it's minimal issues.

Side Note- I would recommend using 2 co2 and one green gas mags in an airsoft game, or two of each if you can, as it would basically fix all the issues, and merit this magazine a 5-star status.

"Have been using these mags for over a year now, and while gas efficiency isn't the best, it gets the job done.
