   Very happy to have a spare mag. Great weight to it.

   Better than the magazine that came with the gun. Though it is a little light, it doesn’t really matter. Does Not Leak! I was so happy when I realized it wouldn’t. The one that came with the gun did leak. CO2 canister stays tightly concealed in compartment. Definitely recommend this to anyone that needs to replace or get an extra magazine for their HK USP CO2 pistol.
   PROS:
   No Leak
   Made From Durable ABS-Type Plastic
   Works

   CONS:
   Light (or could be PRO if that’s what your looking for.)

   I purchased one of these from a Marketplace seller. It arrived with the wrench, used, as expected. It started hissing the minute I installed the cartridge. Within a day, a full CO2 cartridge was empty. I returned it to for refund. I purchased a 2nd from umarexoutlet.com Warehouse Deals. This one said it would arrive in original package…it didn’t. Also didn’t have wrench, but DID hold gas. I have left it pressurized for weeks and come back to it with the gas still in the cartridge. I ALWAYS put a large drop of Pellgunoil on the cartridge tip before I puncture it. This is highly recommended for all CO2 guns. It will keep the seals soft and will not hurt the gun. CO2 can be stored for a very long time this way without drying out the seals.

   ADVICE: This mag is your only option for this airsoft gun. So…you have to roll the dice. I recommend you buy it from umarexoutlet.com or a prime seller with free returns. You probably have a 50/50 shot of leaking. I’ve read that you can fix the leak yourself…but it’s a lot of hoops. Buy one, if it leaks then ship it back. Rinse, repeat until you get a good one.

   this is useless it does not lock inside the gun,
   It looks like the real one but it does not fit my gun it keeps falling off every time I put them inside the gun it’s useless and loose you put your hand at the bottom and hold you were gone

   Works well with my umarex H&K USP. Mags are a bit pricey compared to the pistol, with the pistol being only $40 and the magazine’s being $10 a piece at the time I bought them, but it’s still cheaper than other pistol magazines. Mine holds the CO2 canister for quite a long time before it leaks out, I put a canister in for one game, didn’t use it, and it was still good a month later at the next game.

   YOU HAVE TO OIL OR GREASE THE TIP TO MAINTAIN A SEAL. I put in a thimble full organic grease with a long screwdriver into the co2 punch seal area. I was able to revive my original now I also have backups for quick swap out.

   This one looks identical to the original except this one slides better and the sprig does not stick.

    I threw away the packaging and I don’t believe that I can return it. Yes I lubricated everything with silicone grease but alas, it was to no avail. Leaks CO2 when inserted into mag. I’ll let y’all know if I’m able to fix it. Update: I was able to fix the leakage. You have to partially disassembly top of the mag. See the attached pictures. Using a flathead, rotate the metal ring on the back counter clockwise. Once that’s out, you can pull everything else out. There are 2 additional O-rings inside there. Get those out too. Wipe down everything really well with a paper towel (including the inside of the mag) and drown it in silicone lubricant. Be gentle with the O-rings. I coated absolutely all of those internal parts with silicone and then reassembled. I tightened down that outer metal ring extra tight and now it works. Hope this helps. I’m not sure how long this fix will last.

    -Update- Like others have said these tend to leak more often than not especially over time. But after quite a bit of experimenting with a couple of these mags I believe the main issue is the o-ring on the front of the gas outlet valve. Leaks with the piercer/inlet valve for me were easily solved by using the Umarex cartridges and some silicone lube when inserting a new one. The Umarex cartridges are slightly longer (I’m sure there are others with similar dimensions but the Umarex are locally available to me) than other off the shelf ones like Crosman so you can get a good seal without having to crank it down and end up over tightening. But I constantly had problems with that front outlet valve o-ring. The one they use is slightly too thin, and seems to harden/flaten fairly quickly. So all you have to do is swap it out for a thicker more durable one and you should be set. I would’ve been happy to pay a few bucks more if they just used a more suitable o-ring in the first place.

    One cartridge did not work it leaked. My son tried all the tricks he read online to fix it, but it still leaked air. I asked to return it and even before I returned it they sent me a new one. I will continue to buy this from them.

    During first use, the interface between the top metal section and the bottom plastic section developed a gap, causing the gun to jam after every shot and making it really hard to insert and eject the mag.
