Cx4 Storm (carbine/rifle) – TLR fits with 1913 key.
Px4 Storm (Pistol) - TLR fits with standard key. NOTE: M lights are VERY loose.
Vertec - New polymer key – 1913
Older aluminum key – GL (Standard).
P-01 - Should work with GL (Standard) key. (based on similar European version)
5.7 (with Picatinny style rail) -1913 key.
Any with rails – GL (Standard) key
Cannot fit Glocks that ARE NOT equipped with factory rails.
USP (full size) HK adapter 69085 with a GL (Standard) key required (NOT INCLUDED).
(compact) HK adapter 69091 with a GL (Standard) key required (NOT INCLUDED).
HK P2000 (new gun) is supposed to have Picatinny rail. (NOT CHECKED)
TLE RLII (1911 with rail) – Picatinny key.
KP345 – GL (Standard) key
SR-9 – GL (Standard) key
GSR or 1911 Style with flat bottom rail - Picatinny key.
ANY ALUMINUM FRAME SIG WITH A ROUND BOTTOM RAIL: Including the P220R, P229R, etc. The Sig round bottom rail departs from the true shape of both the 1913 and Universal standards and may cause an improper fit. The TLR will work with the 1913 key but THERE WILL BE DAMAGE to the finish of both the gun and the light. The retaining screw must be TIGHT.
SP2022 - Polymer frame. Same comments as for aluminum frames, EXCEPT that the polymer frame is a little thicker and does not show marks from a clamp because it is molded from black material. PER SIG, the TLR with the 1913 key works.
SMITH & WESSON:
On the TSW and 99 models, the slot is too far back for the standard key and requires the special S&W key. There are many different models of TSW, but as long as it's a TSW WITH A RAIL, it uses the S&W key.
Smith & Wesson M&P autoloader (new gun) takes the Picatinny key.
SIGMA – Cannot fit.
Operator (1911 with rail) – Picatinny key.
XD (4 & 5 inch barrels) – GL (Standard) key. Cannot fit 3” barrel.
99 - New (2004 models) FULL SIZE ones are nearly the same as the S&W 99 and use
the S&W key.
Older ones (no slot across the rail and the side grooves CLOSED in front) cannot be fitted with a TLR.
99 Compact – Cannot fit. Rail is too short.
P22 – Cannot fit. Non-standard rail.
