Included Mount Kit with Key Paddle Mount
This package includes a complete mount kit featuring a key paddle mount. The key paddle mounting system allows for quick and secure attachment to the pistol’s rail while maintaining a low profile. The included hardware ensures a rock-solid connection that can withstand the recoil of the P365 series without loosening during use.
Compact and Lightweight Design
The TLR-3X is engineered to be as compact and lightweight as possible, making it an ideal choice for concealed carry pistols. Its small footprint minimizes the impact on the pistol’s overall concealability while still providing powerful illumination when needed. This balance of size and performance makes it an excellent option for everyday carry users who want a weapon light without compromising the P365’s slim profile.
Powerful Illumination
Despite its compact size, the TLR-3X produces a bright, focused beam that provides excellent target identification at close to moderate ranges. The light is optimized for the typical engagement distances associated with concealed carry and home defense scenarios, offering clear visibility without excessive splash or bloom.
CR123A Battery Powered
The TLR-3X is powered by a single CR123A lithium battery (included). This battery type provides excellent runtime and reliable performance in a wide range of temperatures. The use of a common CR123A battery also makes replacements easy to find when needed.
