Blade tech makes a good IWB holster that won't close up on you and make it easier to reholster. I don't recommend small of the back carry, but if you are comfortable with it, more power to you.
I've got Split Decision that I use with a Glock 26 to carry right above my right rear pants pocket and it's pretty comfortable. I like it for when I have to drive a lot because it seems to work well with the larger side bolsters on my seats.
