I think I want an Inside the Waist Band (IWB) holster, kydex or leather, with a covered mag release. I had an exposed-mag-release Kahr self-eject a magazine once, and that's the last time I want that to happen.
That's part of the reason I bought the H&K P30S - trigger guard paddles for mag release.
I have no reason to doubt Tony at JM Custom Kydex when he says they don't cover their mag releases, partially because the holster can flex and activate the release, but that seems a little theoretical to me while my memory of the Kahr magazine on the floor is more of a reality.
Who makes a good IWB holster that covers the H&K trigger guard mag release?
