Now you can be an example to the Gov't of how high capacity guns don't cause people to rampage

Well, the thing about the trommel is that it's basically impossible to load more than 10-12 rounds without the loading tool anyways.

So there's another $500...

I guess this probably counts as necroposting, but I'm very curious;
what is the technique to shooting a Luger with the snail mag? Do you have to hold it some special way? Or just do a ton of bicep curls before?

Well, the trommel was only ever intended to be used with the stock. Using it just as a pistol would be retarded. You hold the pistol with your right hand, stock in the shoulder, left hand under the drum. It's actually pretty awkward.

On a side note, I've picked up a reproduction holster / stock and found a guy in Europe selling a loading tool fro $600. Sadly thats a good deal, the tools are 3 times rarer than the drums. And the drums are rare!
