The Lawman is just a beast of a .357 snubbie. The cylinder is long enough to accommodate the 358429 SWC bullet. There's also enough mass to handle even an Elmer Keith level of 2400. The only downside it is tough finding a good holster for one these days.
I've tried a number of belt holsters for the Lawman and most have proven disappointing. With the short barrel it is quite top heavy and the gun wants to twist away from the body, particularly in a high ride style holster. A holster that goes across the frame, cylinder and full trigger guard like the El Paso pictured is about as good as it's gonna get.
If I was going to spend a lot of time sitting, like in a car or behind a desk a horizontal shoulder rig might be OK if you could find a harness that didn't wallow around too much. I really like the gun, it is a beast of snubbie, but paradoxically, a four inch gun is easier to wear comfortably.
