It's all personal preference, but I don't care one bit for the hard plastuc holster, either. There all kinds of reports on here of the BB launching out of the plastic holsters.
You'd very likely prefer one of the leather holsters, just make sure it has the sleeper magnet. Look at the forum below on hardware etc for ideas.
