That's an intriguing rig and holster design.
I like the idea of a laser sight for use in low-light conditions, even on a small revolver or pistol, but I have to admit that I'm still somewhat leery about the sustained accuracy under recoil of laser designs which are simply bolted or screwed onto the gun and/or trigger guard rather than being fixed to a dedicated rail (e.g., Uni-Max), integrated into the grips (e.g., Crimson Trace), or installed as a replacement for the guide rod (e.g., LaserMax). It will be interesting to see how this new design holds up under hard use.
