Thanks for all the replies. I went ahead and ordered one with the tuckable option and I have tried it for several days in several diffent positions and I'm not happy with it. The holster does not fit the specified gun, unlike the one in the video, it lets the gun move back and forth in the the holster. The holster itself tends to move from a canted position to straight up vertical. The combination of these two means the gun is never in the same position and I have to search and regrip to draw. I tried tightening my belt but that made it very difficult to lift my shirt to draw the pistol. The welting aroud the edges is the same sticky material that secures the holster and tends to grab the shirt tail making it difficult to lift the shirt. This also pulls the holster out of position, again causing a fumble, search and regrip situation.
On the plus side, the material and sewing or good quality and the original model without any options should work. Provided it fits the gun correctly.
If you decide to try one be sure to read the return policy--- before--- you order. Remora considers their tuckable option a modification and will not accept a return.
