I'm a big fan of Galco, particularly the Avenger for my 1911's, I have 3 for Defender, Combat Commander and Government. Galco recently made a custom Combat Master for my 3" 629 Trail Boss. When I do have occasion to carry a longer barreled N-frame I have from way back two Roy's Custom Leather Hidden Thunder shoulder rigs with several different holsters to interchange. I also own something for my 1911's that I always said that I'd never own, until I tried one and that is a Fobus paddle. It's quick and easy and carries any barrel length.
Several years ago I started using a Gunfighters Inc rig for trips where I might need really quick access. If you haven't seen them you should check them out, keeps my pistol and my bear spray right where they need to be and doesn't interfere with a backpack or pack frame straps.
I literally have a storage tub full of different holsters and rigs, everything that I own I have at least one way to pack it.
