MD Arms have just started shipping their new 20 round drum magazines for the Siaga 12 shotgun. They cost $215 (+ $3 handling fee).
It look like they have only made enough to satisfy pre-orders and are now taking pre-orders for the second batch.

Just got in the latest batch of Saiga 12 drums. I am told these are the best batch with a few small upgrades that allows them to be the finest Saiga 12 drum available. In stock and shipping same day. Here are a few pictures of them: http://www.hkparts.net/shop/pc/Saiga-12-MD-Arms-12-Gauge-20-Round-Drum-2p971.htm

0 0Harold: You have problems with PowerMag700? Specify your problem. 
0 0I guess only for US citizens. For EU there is only one option.
Why? Because you can’t buy it directly – us laws limitations.
Can it get 3” shells? I don’t think so.
0 0I like to ask you if the MD-20 drum fit in Molot Vepr 12 and if is working with it how can I purchase it to Greece?
Thank you!
0 0Drum for Molot Vepr 12? There is only one producer: Maxrounds. You can buy completed PowerMag for Molot if you want to. But you have to write to them. This item is only on request in Competitor’s Packs.
0 0I think they are to big and have seen them jam alot, unlike my new wraithmaker 20 rounder that never jams and is almost an inch smaller around
0 0Did you try 20rds mags from maxrounds? http://www.maxrounds.com
0 0“…There would not very much overseas demand. The initial design costs would be a big percentage of the cost.”
I don’t see any demand for a 20rd Drum with a $200 price tag unless you’re just dealing with full auto ammo eating folks who can’t take a moment to change 10rd mags.
A better name for this contraption would be a “rolled magazine”. A drum of this size should hold at least 30 rounds.
0 0gyrfalcon, it is a limited market. They are being made in the USA not imported. There would not very much overseas demand. The initial design costs would be a big percentage of the cost.
0 0You would think they would make a drum with more than 20rd capacity considering 10rd magazines cost $50.
Who would want a 20rd Drum when you can get 40rd’s of magazine capacity for the same cost?
0 0gyrfalcon, You don’t get out much do you!
0 0I would like to purchase a few Saiga drums for my 12G Saiga shotgun. Who do I order from?
0 0You can buy PowerMag from Maxrounds
0 0I would be interested in ordering a drum can someone please advise as to how I do that. Thanks T. Alexander
