Spartan rail mounted 5mw red laser sight - LaserMax Spartan Adjustable Rail Mounted 5mW Red Laser Sight

Product works well and performs as advertised. Switch does tend to pop on if not in suitable holster but that was known upfront. Has maintained laser position after several hundred rounds fired. As a senior citizen it better allows me to focus on the target with both eyes open. In a confrontation this means better overall situation awareness.
