Warren's probably the man to ask about mags for the Bell. Someone asked about using TM mags, but no public answer was given.

I've owned one of each, and all in all I like the WE better. Bell will cost you less, but they are really hit and miss quality wise, and if you buy one I would recommend using the Marui mags rather than Bell spares. By contrast the two mags which come with the WE haven't let me down, despite having nine less rounds per mag.
Friends meet to part - love laughs at faith;
True foes, once met, are joined 'til death!
I'd recommend the Bell full metal - the mags are fine and the gun is easy to upgrade. For parts and mags, I can recommend www.KHMountain.com - they're good on price and quick on shipping.
Mine has an Element 150% spring in it along with a metal chamber. Accurate and kicks like a MoFo on green gas.
Oh, and they're really, really cheap!
I'd recommend nothing but green gas for a full metal .45, as lower powered gases struggle to cycle the slide.
When I want your opinion - I'll tell you what it is!
