I expect to mount some holographic sights on some handguns in the near future, I often open carry outdoors, currently with iron sighted handguns and would like to continue to do so with the red dot equipped handguns. What are people currently doing for holsters in this situation. The guns I may carry: 629 5in, MK III 5.5in, Contender 10in.
The sights may be fastfire type or tube type.

Any advice, pictures, makers (custom or OTC) models etc. would be appreciated.

Thanks
