I have a Galco Miami Classic myself. I rarely use it as I don't often wear a coat but it is a nice holster. Andrews custom leather has some very nice shoulder rigs but they will run a bit more than the Galco.
Galco Miami Classic II for my G29SF and my G30. Use it on long trips while driving. It is very comfortable. Galco has good quality and reasonable price. There are better ones but Galco seems great to me.
