I have bought one before and it still works after many years. Batteries are easy to change and I found a holster for my Sig P365 and Streamlight. It’s a great combination, your favorite sub compact pistol and this Streamlight make a great carry pistol for CCW or open carry where it’s allowed.
Streamlight Design for the P365 should be that the body of the light should not physically extend past the barrel of the gun and it could be much much more brighter, especially for the price of $100 or more! ...& I cannot find a leather holster for this configuration! P365 + Streamlight TLR-6
