The venerable Streamlight is famous for its durability and features, and likely the most widely recommended weapon light in existence. Coming in at a price we can all get behind, the TLR-7 A is a no-brainer for your pistol, mounting easily beneath the barrel on your weapon's picatinny rail.
 
Why the TLR-7 A is the right choice for your handgun:
Customizeable ambidextrous switches to suit any shooter's needs
At only 2.58" in length, this compact light will fit neatly under a wide range of pistol sizes
Streamlight is THE go-to source for weapon lights for a reason. They make excellent, reliable products without charging absurd prices.
