Poorly designed key for 365xl and no alternatives in the box - Streamlight TLR-7 X Sub Ultra-Compact LED Tactical Weapon Light

This light states it is for the P365 and 365XL. It came with a key. But the key has no raised bar to fit into the rail slot. The 365XL has a slot. The directions state that a key must be used to avoid the light falling off under recoil. At first, I thought I just received the wrong key. But, it appears the one I got was the intended key. I had to spend another $12 on Amazon to buy a properly designed key for it. There is no assortment of keys on the box. Just one. It should come with at least the original plus one with the raised bar. The light is also larger than I expected. But, it produces a reasonable amount of light - a lot more than the TLR-6, albeit not highly focused. But, your old holster won’t work. This light is longer and wider.
