Magazine type for SP01 Shadow

[Stealth]

Being new to sports shooting, I'm coming to terms with learning not only a new language but also a new set of technical information.  This is where I need your help: I'm wanting to purchase a double magazine holder for personal carry and am confused in relation to what type of magazine is used in the Shadow; is it a single or double stack, and what does this mean anyway?  Thanks Guys, I knew I could rely on you!  Richard

It uses double stack mags. Basically the width of the mag allows the 9mm rounds to sit just about side by side. If each round sat directy on top of another round it would be a single stack mag like used in 1911 pistols.

Thanks for the clear and precise information.  Much appreciated.  Richard
