I had to call my SIL for this. He likes his Alaska hunters chest rig from MTR Custom Leather for several reasons. First, the holster rides lower than his previous chest rig; and second, it is anchored to the belt.

He also said he likes the fact that he can use different holsters for his revolvers or pistols.

When he goes fishing or hunting in Alaska, he carries a 454 or 10mm for the hungry bruins protection.
