It depends on how form fitting the holster is, and how much give there is in the material. If it is some softer material then some will. I know that I have holsters for 4" Redhawks and 4" Model 29s from Milt Sparks, where the leather is very hard, and the Redhawk will not fit in the Model 29 holster. However the Model 29 will fit in the Redhawk. So it just depends.
