One Awesome Tool
This is one awesome weapon light. Truly lights up the dark. One thing, the X300U-A ships with the Universal Rail Mount. There are two rail mounts that come with the unit. Universal Rail Mount and M1913 Pic Rail Mount. One would think the Universal Mount equipment would be used to attach to a Glock with the Glock Accessory Rail. This is true EXCEPT for Gen5 Models. Though not a true 1913 Rail use the rail equipment Marked with P For M1913 Picatinny Rail. This fits my G45 Gen5 perfect. No play in the unit whatsoever. This info is not in the user manual and some of the You Tube videos you see claim the unit is loose on Glock. Great unit and the news needs to get out. I had to call Surefire customer service to get the info. Great Product.
