Editing Tactical light (section)

=== Standard form factor and light bearing holsters ===
On most [[handgun holster]]s, the firearm is held in the holster via the [[trigger guard]], either via a locking mechanism or simply by the holster being a bit tight in that area and holds or clicks the firearm in place. On handguns with lights, however, it is often not possible to make a holster that retain the firearm by the trigger guard, and most such holsters therefore retain the firearm firmly via the light.<ref>[https://blog.werkz.com/?p=17 Six Things Your Light-Bearing Kydex Holster Will NOT Do – Werkz Blog]</ref> As such, ready-to-use light bearing holsters not only have to be made for a specific handgun model, but also a specific light,<ref name="policeandsecuritynews-2018">[https://policeandsecuritynews.com/2018/01/24/selecting/ Selecting a Light Bearing Holster | Police and Security News January February 2018]</ref> or at least for a light which shares the same or roughly the same form factor. One example of this is the SureFire 300 and 400 model series, which have retained the same form factor despite receiving numerous modifications over time. Pistol lights sharing the same form factor gives the possibility to upgrade lights to newer models and continue to use old holsters, as well as giving better aftermarket support for holsters. Some holsters can safely accommodate different types of lights.<ref name="policeandsecuritynews-2018"/>
