One of the things that I have found to be the more difficult aspect of gun ownership is figuring out if a light will fit on a particular handgun that I have. I have been misled by Amazon reviews and I honestly don’t want to modify my lights to make them fit on one specific gun. In this post I will be keeping track of what lights won’t fit on which guns. I will also add in WML/handgun combinations that haven’t worked out for you, just shoot me a message on Facebook!
Note: The list is based off of stock compatibility. For instance, the TLR-1 can fit on an HK USP with the help of another attachment accessory; even though it can with that attachment accessory, the light itself is not actually compatible with the firearm.

  1. Streamlight TLR-1
    Does not fit: Heckler & Koch HK45c, Heckler & Koch USP, USP Compact, Walther CCP M2, Beretta PX4 Compact
  2. Olight PL-Mini
    Does not fit: FN Herstal FNS-9c, Heckler & Koch HK45c, USP, USP Compact, Walther CCP M2
  3. Streamlight TLR-7
    Does not fit: Heckler & Koch HK45c, USP, USP Compact, Beretta PX4 Compact
    Update: Light does fit on the FN FNS-9c with the proper rail insert but it is a tight fit.
  4. Surefire x300
    Does not fit: Walther CCP M2, Heckler & Koch HK45c, Beretta PX4 Compact
