TMC W&T Kydex Quick Draw Holster for Tokyo Marui M870 Breacher Airsoft Shotgun
(Color: Black / Belt Loop w/ QD System)

"I would give this a good review except that the mounting screw pattern doesn't match up to Tech-Loks or similar mounting systems. You have to use the clip-on mount, which is poorly designed and doesn't fit well.

I will need to drill new mounting holes in my mounting hardware to make it work. So my review is neutral.

Other than that, it's a decent product. Holds an 870 well, clamps around the gun's magazine and barrel between the receiver and the pump. Won't fit the CYMA "870" tri-shots, but Marui 870s lock in just fine.

Just for fun, I tried it with real-steel 870s and an Ithaca 37, and it worked.
