I carried my 442 in a cheap uncle mikes for a long time. But it wasn't really the right size for it. It is for a medium auto and it kind of swallowed up the gun. I actually kind of liked that because it hid really nice that way. But made the draw a bit more difficult than a holster that rides a little higher. That was at 4 oclock.
Now I carry it AIWB in a Galco leather holster. I'm not even sure of the name of it but it works perfectly. That particular holster I didn't really like at 4 oclock. Well, with the grip I use. I use a bigger grip than a boot grip. Hogue Tamers. So it prints and sticks out more. If I just had boot grips on it, it would probably be just fine at 4 oclock.
Those are the only two holsters I have experience with.
The Galco is marked: C139L STO158
