TS,
First thing I want to say is the SmartCarry type holster will have you adjusting all day long, as the "holster" does not hold the pistol securly. This is common with many similair holsters and especially these that use only the tension of their own belt to secure the weapon in one position. Now I did watch the videos and did some checking, but based on my experience, I personally have had bad results with such holsters. If you have to keep adjusting the weapon in the holster, then carrying concealed is compromised.
I wear a suit and tie most days, or go without the full suit maybe one day a week. I have been using the Galco SkyOps for the last several years.

The reason I have used this is I don't find myself adjusting; it holds the pistol securly and doesn't ride up or down. The clips are small, yet extremly strong. I do find it best to run the belt through, but the clips can be worked over and under the leather belt. It does depend on how flexible the belt is, but a belt that is too flexible shouldn't be used to secure a holster.
The holster is a butt forward design, which has the butt more in line vertically with the torso. This eliminates the butt sticking out and the glaring printing. This angle also helps with draw when worn between the three to five o'clock position.
The clip system is secured to the holster near the bottom of the holster, so you can tuck your dress shirt in for maximum concealment. Only a small part of the plastic from the J hook is visible, and pretty much disappears on a back belt. For further concealment, I wear my cell phone carrier next to it, as it helps conceal the J hooks and draws the viewer's attention to the cellular phone carrier.
Prior to this, I used a Kramer IWB with the FBI tilt for my SIG P220 or P226. Outstanding horsehide, the only issue I ran into was the loops could print against the the wool of a suit jacket. The pistol itself was tight against the body. If I could have the same type of J hooks that Galco uses installed, I'd still be using the Kramer.
