Funny, I just got the same holster, except it's the model that's not tuckable. Overall I like it, but I have two gripes.
1- It's a good fit but it's not a perfect fit. The gun doesn't go down into the holster quite deep enough to cover the entire trigger area, the trigger is effectively covered though.
2- I don't like the placement of the tension screw. You'll notice it's under the trigger guard and when it's clipped into my waist it creates an extra bulge, or I guess it's kind of hard to explain, takes up more space than it needs to.
I'm not disapponted with it, for $25 I consider it money well spent to give me an idea what I do and don't want in an IWB holster.
PS: The retention is good, and the draw is smooth. It's not really good at one handed re-holstering.
