I don't own a Theis and I am sure that it is a good holster, but there are numerous semilar holsters of this type on the market and I own several. But, what works for me may not work for all. I have several boxes full of highly recommended, costly and well made holster that don't work for me collecting dust in my garage. I hope my wife never sees this posting. LOL. I have found that the Cross Breed Super Tuck and the Galco King Tuk work the best for me. Keep in mind that a holster is only as good as the belt.
