NovaJet laser pistol - frame only, 10 watt output limit. This sidearm series is currently in R&D for frontier markets.  The relatively benign F10W variant has been developed in ICC-compliance to test the form factor.  Won't be worth a lick in a gun fight, Earth cowboy...
 
The NovaJet F10W is a shell that holds a linked pair of FlowToys Capsule LED modules (buy one Capsule Link per pair; get with O-rings, not bumpers). The LED capsules are not currently offered by Starside Armory, and must be provided and loaded yourself. Developed in close coordination with flow instructor Xander Paris, we included the following features:
 
Transparent TPU frame for durability, impact resistance, and light transmission
LED capsules+cylinders rotate to protect charging ports (not waterproof)
LED capsules can be loaded/removed from the rear without disassembly
Rear capsule button activated by pressing hammer
Streamlined features for a smooth and quick draw
Orange tip attachment
Ambidextrous safety can lock trigger in either a safe position or pulled position, slightly altering spin characteristics*
Functional picatinny rails*
Spring-loaded trigger*
Can be fully disassembled for maintenance (2.0 and 2.5mm hex wrenches required)
 
*Features may not be very useful, but were added as a matter of course.
 
This prop must be used responsibly.  Be mindful of your audience and what they may or may not be comfortable with.  Be smart and respectful about where you point it, where/when you take it out, and how you act with it.
 
As with all frontier arms, Starside Armory is compliant with ICC regulation.  The F10W prototype contains no weapons-grade laser components and as such cannot be modified to remove the inherent output limit.  If the project moves beyond this public test phase, unrestricted units will not be available in ICC space.
