When I bought my CT Red Laser from CT for my Shield 1.0, I got it in package deal with the CT offered Blade Tech holster. I like the CT. I am not so sure about the Blade Tech though. It has no adjustments. The Shield rides higher than I like when on my belt, however, I have not been able to find another choice yet.
Take a look at the Hidden Hybrid line (Hidden Hybrid Holsters | Made in the USA | Concealed Carry Holster).
They have both OSW & ISW holsters listed for the Shield with a laser.
I've have three of their Double Clip IS & OS models, one being for my Shield. They're highly concealable and comfortable for all day wear.
