Will this holster accommodate a red dot optic?

Depends on where the optic sits. It will work with some setups. Feel free to buy and return as per our money back guarantee if it does not work out.

Hello, What light/laser combo would you recommend with this holster? I purchased an OLIGHT Baldr Mini 600 Lumens Magnetic USB Rechargeable Weaponlight with Green Beam and White LED Combo, Compact Rail Mount Tactical Flashlight with Adjustable Rail (Black) and it is too wide for the holster but was recommended as "frequently bought together".... don't see how..

Frequently Bought Together doesn't indicate cross compatibility. However, the Olight Baldr Mini (and most pic rail lights) is compatible with HC11. This video may be helpful: https://www.youtube.com/watch?v=4r5C_SXb8Jc

I have A S/W 1911 compact (3 inch barrel) with a cc3h grip and rail on it with a sure fire light. Is there a holster that will fit this rig? IWB or OWB? Thanks

The HC11 should do the trick. Haven't tested with your light specifically, but it is compatible with most lights.

What is the grip texture gonna look like they show 3 separate style textures in photos of this particular link and the grey and tan look different shades

It was a mistake. Images of the CC3C were showing here. We replaced them with the correct images.

Will this fit a double-stack 1911?

No. The HC11 is designed to holster a weapon that has the CC3H or CC3P installed both of which are not compatible with double-stack weapons

Does holster fit 1911 with itself rail? Or it has to install with CC3H grip only to fit the holster?

The HC11 is designed to holster a weapon that has the CC3H or CC3P installed (both of which are not compatible with weapons that have a built-in rail)
