I don't know about a holster or about your model, but even though I said it was two cases, it really is very slim and adds very little to the profile. I'm still able to carry my Storm in my pocket with the full case no problem. Still, I don't know about your model or what type of holster you have, but the website does have model specific cases. As well, they took no time getting back to me about my customer service issue, so it wouldn't hurt to eail then with a question. They're obviously very service oriented at Incipio.
