Glock 19 holster with X300

A Glock 19 with a SureFire X300 needs a holster cut for both the 19 and that light. A plain 19 holster will not close over it. A TLR-7 holster will not retain an X300. We sell parts, not pistols. Compact rail light is a different page — Glock 19 TLR-7 holster.
The light. X300U-A is the rail-lock 1,000-lumen Ultra. X300U-B is the thumbscrew version. X300 Turbo is less lumen, more candela (tighter hot spot) — still an X300 holster body, A vs B is how it clamps. Tan vs black is color. Vampire is IR plus white; holster catalogs still treat it as X300-size. This light hangs past a 19 muzzle. Full-size 17/34 duty pair: 17/34 lights.
The holster. IWB: Bravo Torsion light-bearing 19 X300, GBRS P1 Glock X300U. OWB range: Bravo BCA light-bearing 19 X300. Duty: Safariland 6354RDSO Glock 19 MOS X300 (coyote and ranger green are in stock). Rapid Force L2/L3 “large light” for G19/X is the other duty-size IWB/OWB family. The title must say Glock 19 (or 19 MOS) and X300. A 17-only X300 shell is not a 19 unless 19 is listed. 19X and 45 share the 19 slide length; still read the title.
Optic. MOS / RMR on the slide is a second cut. 6354RDSO is optic-ready. A Torsion X300 IWB is not automatically MOS. If a dot is on the gun, the holster must also say MOS, RDS, optic, or the sight name — Glock MOS red dots.
Search GLK 19 X300 or Glock 19 X300 holster. Supplier titles keep X300, X300U, and GLK. NSW-style 19 + X300 is the compact duty pair in what gun Navy SEALs carry.

Questions
Will a Glock 19 TLR-7 holster fit an X300?
No. X300 is a full-size duty light. TLR-7 is the compact rail light. Different holster bodies.
Is X300U-A the same holster as X300U-B?
Usually yes for the holster shell. A vs B is how the light clamps to the rail (lever vs thumbscrew). Turbo is still X300-size. The holster must say X300.
Does a 17 X300 holster fit a 19?
Only if the title lists 19. A 17-only duty shell is longer. 19 MOS X300 Safariland 6354RDSO is the 19 cut.
Do I still need an RDS holster if I have a MOS red dot?
Yes. Light-bearing and optic-ready are separate cuts. 6354RDSO names both. A Torsion X300 IWB is not automatically MOS.
