Big,
When you get a revolver holster with the cylinder above the belt line, the length of barrel and quality of leather becomes becomes very important. As does the style of holster, with regard to the location of the belt loops.
The longer the barrel, the less "floppy" the holster will wear, as the portion of leather below the belt will allow your hip to rock the butt, inward. You cannot adjust for this, as you barrel is fixed, and short. But quality leather can account for this.
Slots that are behind and in front of the holster body will allow the belt to pull the gun in tighter to the body. The original term for this was pancake style. The half pancake style would be one belt slot that hits the gun at frame/cylinder, with a slot behind the holster. This is usually a tad more comfortable than a full pancake, but usually a tad less pull into the body, and concealment.
While I have never owned a 442, I do have and have owned other, similar guns. I have had really good luck with De Santis leather revolver holsters, in the pancake style. These all have had a thumb break, as this is typically needed when the cylinder and gun weight get higher on the hip. They are also priced reasonably well. The leather is usually on the thinner side, but style and construction are very good.
