If you are looking for a good belt holster and case combo I just purchased the INCIPIO NGP Matte Semi-Rigid Soft Shell Case and I am using it with the Seido SURFACE Holster. I did not use the Seido Surface case because I did not like that it is in two pieces. I use a Pro Clip USA holder in my car and I did not want the two piece case pulling apart when I remove it from the holder.
