I am in search of a shoulder holster for my new Model 69 4.25" L Frame .44 Mag. It needs to be concealable so a cross body chest style is not suitable. I prefer a horizontal carry holster but vertical can be ok. Want a quality holster.

This revolver just does not show up in the "Search by Gun" listings among holster sellers. I've tried comparing specs for this revolver with other S&W L Frames but in the couple of tries there have been minor differences in dimensions that concern me about fit. Galco makes holsters for a 4" L Frame but say that the 4.25" won't fit.

Recommendations will be greatly appreciated, especially if you have actually purchased and used a suitable holster for this revolver.
