So I'm very new to GBB pistols and recently got myself a WE M92 FS. Filling up the magazine with WE Green Gas for about 5 to 7 seconds lasts about 1 and a half magazines (25 BB's in each mag).
Is this normal because I would have though that one refill would last at the very very least 2 mags and more reasonably 3 mags.
It's not exceptionally cold and even if I don't rapid fire it won't last 2 full mags.
How long should it last?
Also, sometimes even when the magazine is empty the slide won't lock back and I can keep firing. This usually happens after rapid firing. Is this normal or is something broken?
