I've been on a long and difficult quest to find a shoulder holster that will conceal a 4" K-Frame size .357. The problem is this. The barrel is too long long for a standard horizontal rig. Galco makes them, but they poke out and aren't really for CCW. Vertical rigs are primarily designed for hunting handguns or at least aren't too easy to conceal. Again, Galco's vertical rig is very nicely-made but is too thick and hangs too low to conceal.
What's needed is something that brings the revolver up deeper under the arm and holds it further back, so the handle pokes out perhaps half an inch or so from the arm. Null makes an excellent upside-down rig, but it is primarily designed for deep concealment of J-Frame size revolvers and small frame semis. 4" revolvers of K-frame size and larger tend to ride rough and cut off the blood.
I recently had a crazy idea that actually seeems to be working. I took the straps from a KL Null shoulder holster and merged it with a modified Uncle Mikes IWB holster for a 4" revolver. I removed the plastic clip from the IWB holster and carefully made two cuts through the fabric holster. Two horizontal cuts about 1/2" wide, one on the front right and one on the back left, did the trick. I then ran the straps from the Null through these cuts and presto, I had an excellent vertical CCW rig. Extraction is somewhat slower than with a horizontal rig, but concealment is far, far better. And it rides better than the upside-down rig with a revolver of this size.
The same trick should also work with Miami-style Galco straps.
