Question: does it actually hold 380 .2 gram bbs?
Document: Feeds really well and quit a few if you crank the spring til it clicks. Solid metal with good weight seems to hold more than 380 rounds more like 450.
This magazine barely works at all. It shoots like 2 shots then you have to take it back out and put it pack in for it to shoot one more. Im not sure what is causing this, the bbs are just not going up into the gun. If you are looking for a mag where you can just go full auto without it running out this is not it.
I bought this because the drum magazine to the airsoft m1928 Thompson is too bulky and uncomfortable to hold while shooting. It works nicely, but the BB chamber door on top is slightly bent. I would return a damaged product, but I would prefer not to get in all the return business so long as the bb's are not actually leaking out of the opening (which is impossible considering there is not enough room for the ammo to escape).
This is a review about the MAGAZINE itself, not the gun or stick magazines in general.I have seen other reviews saying things such as "Doesn't work", "Broken", etc. These are not true. I bought the Cybergun M1A1 Thompson and this with it. I was surprised to see that my Thompson came with one. It was on the box, saying that it came with the 47 round or new, metal 380 round magazine.As the box suggested, the magazine is actually metal.
This is a stock magazine so it actually holds around 400 rounds. Works perfectly. I intend to by a couple more.
Just like the one that came with the Thompson. Works the same, fits the same. Got 2 so I could fill out a 3 magazine pouch.
This magazine is well constructed and fits well in my Cybergun AEG Thompson M1A1. It comes with ZERO instructions. At first I didn't notice the flap door to feed the pellets and attempted to use a speed loader as with the stock magazine. Of course I could only get about 10 BBs in before it stopped feeding.
)About this magazine:  Be sure to fill it with a funnel, into the little flap door on top, not down the feed hole with a speed loader. Also, be sure to wind it up all the way with the thumb wheel on the bottom; that's how the BBs get up into the gun. Don't worry about over-winding;  when completely wound you'll hear a slip clutch, which prevents over-winding. Just stop at that point.
The magazine feeds the rounds in short bursts, and fires nothing between them. When I wind it all the way, stick it in the gun, and hold down the trigger, the gun would fire a few rounds, then stop because the mag isnt loading the rounds, then start firing again, all before I let go of the trigger. These failures are completely unpredictable; some days it fires with very few breaks, others I have trouble squeezing out a single shot, but it never works perfectly.
when i got this item i was happy i can play with my thompson but the srping is broke it is ok
