Unfortunately Streamlight does not provide the size of the hex wrench, however the size you need is included with the TLR-6.
Unfortunately the Glock models will not fit the Polymer80 frames due to the difference in rails and trigger guards.
Updated information shows that it will not. None of the TLR-6 models will work for the Shield EZ firearms.
The Streamlight TLR-6 C4 LED Weapon Light will fit a Sig 1911 Fastback Emperor Scorpion. You will need Streamlight TLR-6 C4 LED Weapon Light model number 69279.
It will not, due to the different frame dimensions difference from the Gen 1 to the Gen 2.
No, this would not fit the Sig Sauer P365XL as it is longer in length than the P365.
Yes, the Streamlight TLR-6 C4 LED Weapon Light for the M&P Shield (MPN:69273) is compatible with the Shield Plus.

The P365 X-Macro uses a picatinny underside accessory rail opposed to the proprietary sig rail found on standard P365 model pistols. You should be able to use MPN:69293, which is designed for railed M&P handguns but should also work with the Macro.
