I also had trouble deciding between the regular and the boot grips, but ultimately decided on the boot grips.
I love them, and they're extremely comfortable when I hold the gun. I've never felt like I needed the extra length of the longer grips, and since they're shorter, it conceals that much easier (I'm 150lbs, so it's tough finding a good concealable weapon).
The holster is an AKJ Concealco holster. He was running behind when I ordered t, so turn around time was a little slower than usual, and it's one thing I had wished I had ordered further in advance (just so I can start carrying that much sooner!). Initially, I felt that the holster pushed the grip into my body a bit too much for comfort, but after the break in period, it's relaxed and now fits wonderfully.
