A fine magazine, although I am only able to get about 17-19 rounds on one charge of gas, and I have tried green gas and propane. On a warm day occasionally I am able to get all 22rds out, but this has happened very rarely. If you have the money, buy the CO2 mags, they are much more reliable and you can get about 64rds on one CO2 cartridge.
-holds about 22rds, which is a lot for a 1911 replica
-only a fraction on the full mag capacity can be fired
-Mag does not hold enough gas to fire all the bbs
-loads the bbs in the middle of the mag (which I find very weird), and the follower does not lock down, so you have to hold it with your finger. KJW gives you a tool to hold the follower down, but I find that it pops off very easily, spraying bbs everywhere.
