There is currently not a BlackHawk T-Series L3D Light-Bearing Duty Holster for the M&P 10mm with a light. You will need to know the specific light you are using to find a compatible holster.
The BlackHawk T-Series L3D Light-Bearing Duty Holster for the Glock 20 with TLR2 will not fit a Glock 20 with TLR8.
Unfortunately, we do not currently carry any holsters that are specifically designed to fit a Glock 40 with a TLR-8. We do carry universal fit holster that would be compatible like the Recover Tactical G7 OWB Paddle Holster, found by using the link below:

The BlackHawk T-Series L3D Light-Bearing Duty Holsters will fit a Sig M17.
Yes, any of the BlackHawk T-Series L3D Light-Bearing Duty Holsters that are compatible with both the P320 and TLR-1, will be compatible with your P320 and TLR-1 HL.
Yes, the BlackHawk T-series L3D Duty Holster will work with a Sig M18 and Holosun 407.
This BlackHawk T-series L3D Duty Holster will not accommodate your Holosun 507. I would recommend using the Safariland Model 7ts 7390rds Als Mid-ride Level I Retention Duty Holster or the 7378RDS 7TS ALS Concealment Paddle/Belt Loop Combo Holster found using the following link:

It has screws at the bottom of the belt loops. You can undo them and slide it onto your belt without having to remove every thing else. When you tighten the screws it holds the belt securely and does not slide.
if things are ordered early enough in the day, there is a chance!
Yes. The BlackHawk T-series L3D Duty Holster will fit any generation of Glock, as well as the Glock 22. You can select a holster that is compatible with a specific light/laser, or without one.
