I like my supertuck*, but the best holster is the one that best; conceals, retains, and allows good access to your firearm, while being comfortable for a full day of packing.
Expect to have a few holsters that don't work out, and budget accordingly. Quality often costs, not just for good materials, but also for the skilled work and customization.
*The CrossBreed SuperTuck works well for me, and is well designed ... it may not be a good fit for you, but it is worth a try, they do have a 2 week guarantee, you should know if it is right in that time-frame, assuming you can carry in it daily for more than a few hours.
