TLR Compatibility List 
KEYS 
GL (Standard) keys fit Glock or “universal” rails. These have a cross slot about 5/32” 
wide. 
1913 (MIL-STD-1913 “Picatinny”) AND 1913 The 1913 key is wider than the standard 
key because the slots are nominally .206” wide. (A little more than 3/16”) The standard 
key will work with a Picatinny rail but the light will move back and forth with recoil unless 
the clamp is very tight. Some guns with a Picatinny rail still need a standard key 
depending on the construction of the actual rail. These will be identified for the 
individual guns when we test them. 
SMITH & WESSON AND TSW/99 keys have the bar extended farther back than the 
other keys. They are for rails having a non-standard (too short) distance between the 
slot and the trigger guard. 
BERETTA 90two Looks like it has a Picatinny rail but dimensions are different. 
Use the 90two key for the TLR. 
Note: M-lights should not be used on the 90two and will fall off under recoil. 
The GL (Standard) system 
key appears somewhat 
thinner than the Picatinny 
k
The Picatinny key is 
wider than the GL 
(Standard) system key. 
The S&W key is a different 
shape than the other keys.
