The Crimson Trace Ctc Defender Accuguard Spr Xd Xdm delivers a compact, rugged laser sighting solution built on the Defender Series platform with a durable polymer body, designed for quick acquisition and reliable performance on compatible pistols. This dual-side N-Gage activation system enables fast, ambidextrous engagement from the trigger guard, while the factory sighting at 50 feet provides a familiar reference point for precise aiming. Powered by either a single 1/3N lithium battery or two 357 silver oxide cells, the unit offers an approximate two-hour laser runtime with a 5mW red output that projects a roughly 0.5 inch dot at 50 feet, staying visible in most lighting conditions. The activation mode is switch activated, allowing deliberate power-on control, and users can fine-tune windage and elevation to align the dot with point of impact. Installation is user installed, with a wrenched size of 0.05 for secure mounting, and the device features black construction complemented by red activation buttons for quick identification. A one-year limited warranty backs this laser sight, making it a practical choice for duty, competition, or personal defense needs where a compact, low-profile aiming solution is preferred.
