I'd suggest this.

You have already identified you want an IWB.

Next consideration should be:
- Leather
- Kydex
- Injection molded
- Hybrid (leather and/or Kydex or Inj Molded)

Another factor may be how it mounts and/or how many clips.

I have a Gould Leather OWB that I use for concealed carry with an over-shirt, Blade-tech with a belt and paddle attachment, AlienGear Hybrid with two metal clips, DeSantis Soft-tuk with 1 large tuckable clip and a Kydex with 1 wide clip (not tuckable) that I made myself.

My vote goes to a Kydex and any can be made tuckable by adding a simple 3" deep 'U' between the clip and holster.

Use some logic for your questions and selection and you will get better results.

You can Google your gun, IWB and then click images on the top of the resulting page. You can see thousands of options.
