L2 is not a long throw light. It produces a lot of lumens for a "wall-of-light" medium flood on high. On low, it produces a lesser medium flood.
Yes the L2 is a bit longer, but not an unwieldy amount more. The length does make EDC on a belt a bit iffy. In my hand, about 1 inch sticks out fore and aft (the head and tailcap, pretty much) when I hold the L2. It is about 1/2 or 3/4 inch longer than a MiniMag.
The head diameter of the L2 is pretty small (just under 1 inch OD, with a reflector diameter a bit over 0.75 inch OD), so the whole package is about the same diameter (no big head getting in the way), but that small diameter head is also why it is a medium flood beam and not a tight-throwing light.
Bigger diameter and deeper reflector usually gives you a tighter hot spot and more throw. The G2, 6P, C2, C3 all have a 1.25inch OD head (more possible throw) and the A2 has a 1.13inch OD head (more possible throw than the 1inch E-series heads).
Long tight throw? A SpaceNeedle Lux3. But that's pocketable in a cargo pocket.
Long tight throw as in 10 feet, or 100 feet, or 100 yards, or 300 yards? Indoors or outdoors? How big are your pockets (physically and monetarily /ubbthreads/images/graemlins/grin.gif )?
You have to decide where to make the trade-offs in size, performance, and cost.
