It's really holster specific.

For example, I have several 1911 holsters and some of them work fine with a 9mm Hi Power and others do not. For some of them the sticking point is the retention strap that won't accommodate the Hi Power's slightly different hammer location and slide width.

I have a couple of K frame holsters that will work fine with a 686, but again that's not universal. In general, it'll work better with an IWB holster where much of the retention comes from the pressure of the belt outside the holster than it will with an OWB holster where the retention often hinges largely on very snug blocking of the holster to the specific revolver.

Similarly, some K frame holsters work just fine with similar sized Ruger Speed/Security/Service Six revolvers and for the most part a J frame holster will work with a similar barrel length SP101.

I've also found my CZ75 Compact works fine with many leather Glock 19 holsters.
