"Review of both green gas and CO2 mags used in my Spartan Imports Glock 17:

I purchased an extra CO2 magazine and it works great. My Glock came with both a green gas and a CO2 mag and one of them had a spacer/follower beneath the spring that limited the mag to 17 rounds; however, you can disassemble the mag and remove the spacer and achieve 23rds. So ignore the reviewer beneath me that complained about mag capacity. Additionally, a real steel Glock has a 17rd mag capacity, so it's not a big deal. These mags are also a lot cheaper than the ones listed for just the Elite Force Glocks, although I highly suspect that they are almost identical. That version just has Glock trades and a baseplate with no fill valve cutout.

Comparing this CO2 mag to the one that came with the pistol and I can see they updated the rubber seal and piercing pin. The original one leaked CO2 if you kept a capsule in for an extended period of time. This was proven when I tested my mag and left a partially filled capsule inside the mag for ~24hrs. Since the pistol was marketed towards MIL/LE, I wanted to see if it would retain gas if I had to simulate an overnight/extended op. The newer released mag did not leak when I did the same test. Note that the newer mag does not have the two blue painted dots to denote that it is CO2 like the one that came with the pistol (included green gas mag had two red dots). However, the faux extended 2 baseplate and the CO2 side cutouts should make it obvious even in low light conditions which mag you are grabbing.

Green gas mag: My only complaint with the mag (that came with the Spartan Glock) is that the baseplate should not have a cutout for gas fill. As a training weapon, it should be as realistic as possible and be utilized realistically in training. Therefore, the fill valve should be covered and not exposed. During training the shooter may be in a sandy, dirty, and/or windy environment in various shooting positions and have to utilize the pistol and do mag changes. This can leasily lead to damage to the fill valve and the o-ring seal (especially since it should remain lubricated with silicone oil). It is not difficult to pull down the retention notch and slide off the baseplate, therefore the cutout is unnecessary.

All in all, both mags work great. With the CO2 mag, I am able to fire 4-5 mags with 17-19 rds before having to replace the CO2 capsule. Regardless of which mag I use, I leave in the CO2 recoil spring assembly because it is stiffer and gives me a more realistic feedback when I cock the slide. The green gas mag is still able to fire roughly two 17rd. mags before having to be recharged. If I swap the spring assembly out with the green gas version, I suspect I would get even more shots for each green gas fill.
