We've partnered with Comp-Tac to design a holster that works with Mantis X2/X3/X10 and your Sig P320 or your Springfield XD/XDM MOD2.
This holster is an all Kydex, pancake style, modular holster that will fit multiple firearms WITH multiple firearm mounted lights attached. This holster will accommodate a variety of "medium" size lights to help fill a greater variety of needs.
Lights tested with the this holster include: Surefire XC-1, Crimson Trace 201/ 206, Truglo Micro Tac, Lasermax Micro. Holster may work with additional lights with dimensions no greater than: 1.1" wide, .75" tall and 2.4" long.
Fits Sig P320 or Springfield XD/XDM MOD2 and the X2, X3 or X10.
Retention screws may need to be loosened and tightened between models, since the trigger guard is wider on the Springfield. The holster is open at the bottom, so holster is compatible for all barrel lengths.
