To me, there is no such thing as a good cross draw holster. I'll qualify that. When I was a grunt Special Agent, I asked the range officer if I could use a cross draw or a shoulder holster. Boy did I get a lecture. From a safety stand point; the gun's muzzle sweeps through a 90 degree arc that puts it in line with anyone on my left side (Im right handed). From a draw-to-fire time issue, that same 90 degree arc takes a lot longer to acquire the target than a standard strong side hip holster. With a strong side hip holster, when the muzzle clears the leather, it's pointed down range in the general direction of the intended target. Much safer and faster.
Later, I went to the range by myself and tried the cross draw and I must say; the old range officer knew what he was talking about. My scores (time & hits) were way worse and I could definitely see the safety issue should a round be touched off premature.
Depending on your intended use, you might consider a good strong side hip holster.
