Which chest rig do you run? Based on the amount of targeted ads I’ve got the last 6 months, the internet really wants me to buy one.
I run the Gunfighters Inc Kenai and the Stealthgear, the gunfighter for my 500 S&W and the stealthgear for my Semi-auto.
Can't really say either is worse than the other, but I also make my holsters work for me, that gunfighters Inc has a bunch of padding stuck to the back so it sits how I want it (I have the grip forced more into my body). The stealthgear has strap pads on all the straps as some of the buckles would irk a guy when training in light clothes.
I've built my own claws for my appendix carry rigs so I can conceal a ridiculously large rig... and so on..
So it's tough to give recommendations really, outside of general advice, because if you are the type of person that won't modify something to be perfect for you, you may hate how something comes "stock."
Stealthgear has more adjustability in angle of gun, gunfighters inc tends to just be a good, straightforward, works... type holster, not mind blowing technology, no gimmicks, just does what it's supposed to do.
And now that I go look, stealthgear has changed their chest rig dramatically... so I'd go with the Gunfighters Inc again if I were looking.
