Another Geind revolver, this one a later model than the previous one I just posted.
As with the EL-522 this one employs the same principle of using flechette (Shett dart or SABOT) shells that have a special resin that the weapon sends a charged jolt into which fires the round. The handle on this one is a straight up combat grip rather that the simulated catalin the previously posted model has. Geind's naming conventions for their shettier designs are by model number only. They're well known for revolver designs.
Forgot to note that I started riffing off old west 1800s revolvers, not modern weapons, when I began this batch of thumbs. I more or less deconstructed aspects of those old guns I found interesting and put them in the TKP blender.
