Surefire XH30 - Best Overall

Image Referenced 313 Tactical

Why pick the XH30 - XH30 outputs the widest beam for CQB, and throws the hot center beam far in the dark for mid range target ID and effective threat control.

Multi-Lumen Intensities - Choose between 1,000 blinding lumens or 300 lumens for different situations that call for various lumen intensities.

Increased Situational Awareness  - The TIR beam spills far and wide to cover a full size human size target from the head to the waistband to see every detail.

Disorient Threats - The added strobe mode blinds close up threats with intense flash and causes disorientation.

Features Flux Defense MP17 P320 PDW Kit

Works great on FLUX DEFENSE MP17 - If you have the PDW accessory kit from Flux Defense, the Surefire fits perfectly on the MP17 module providing this converted PDW P320 with the best weapon light capability

NOTE: If you already have a holster for the X300U, the XH30 will not fit due to the difference on the front lens.
