In addition to the recommendation above, the CT Web Site, shows two compatible holsters for a Shield with their laser, one a Blade-Tech IWB and one a DeSantis leather.
Don't have first hand experience with any of the above, but provided FYI.
Good luck with your choice and enjoy the Shield. Parting advice would be to buy ammo and magazines now, they will probably not be as available or reasonably priced by this time next year.
