The advantages of the chest carry rig are numerous. One is that it's very adjustable. You can position it as high or low as you want and how far around front or back you want. It is easy to get comfortable.
The chest rig is super fast off and on in case you want to be rid of it quickly. Stopping at the gas station restroom with the need to run in for an unexpected relief stop it might be easier to slip the chest carry rig off than a belt holster. Running into the Post Office or the like, stops like that where easy on and off matter.
A feature I appreciate is the ability to adjust it to whatever clothing you are wearing and current weather conditions. You can wear it over a thin t shirt or over the bulky cold weather jacket. If it is raining or snowing the gun can be worn under a jacket or rain suit jacket and yet still be accessible quickly. Jump on the quad in dusty conditions and just throw a shirt or jacket over the rig. Super versatile.
Regarding accessibility, should you find yourself pinned on the ground the gun is right there on your chest. I have been pinned on my back before and if it would have came to it my strong side belt holster handgun was hard pressed into the ground under me. No way could I have pulled my pistol no matter how desperately I may have needed it. I was fortunate to resolve my issue with a five D cell Maglight using the old school mash 'em technique. Later I had to clean mud and fine grit out of my pistol magwell and grips that got packed in during the tussle. In a hunting situation the same thing could happen if a big hairy long clawed, sharp toothed critter got you down. The chest rig keeps the gun under your hands instead of off to the side as a strong side belt holster does.
And for working I find the chest rig very comfortable. I use the gutless, debone, quarter and backpack out method to get my game out of the timber. I have never noticed my handgun in my chest rig when working on game. It is there, but not in the way ever and has never bothered me while doing the work. My experiences and thoughts on the chest rig.
