quality belt holster for Droid Mini or S4 Mini

[smallphone]

I'm looking for a smaller smart phone, and have narrowed it down to the Droid Mini or the S4 Mini. I will need to wear this phone on my belt, so I ordered a Otterbox Defender for each model.

The Otterbox definitely makes each phone much larger, and the belt clip seems flimsy. I'm curious if anyone has experience with different belt holster cases, or has any recommendations.

Thanks.
