Things I liked: These are the stock Cybergun MP44 magazines according to their packaging.
Things I would have changed: I'm curious to know if they perform any better than all-metal magazines I've seen that hold more for less $. Anyone?
Things I liked: Stock P08 magazine made by WE.
Things I would have changed: Capacity.
What others should know: Contrary to the other review on this site, this is not a different or "better" magazine than the stock WE magazine that came with your pistol. It is the exact same magazine. That being said; Yes, get a spare :)
