Another vote for the Gunfighters Inc Kenai. I wear mine under a Marsupial bino harness and forget it’s there but can still draw quickly if needed. As mentioned above, I too like having a pistol on me in the event I drop my pack for whatever reason.
There’s a couple different mini chassis that they offer. The M5 mini chassis on the LRH requires bottom metal such as Hawkins to function. I’m not sure if the mini chassis you want is available on the LRH.
I got the tripod chaps from Fehu outdoors and stuck a piece of Velcro on the back of the remote. Works great. Also got a Rifles Only data card holder so I can keep the sound list handy. You can see the card holder in this picture. The remote isn’t pictured but goes on the Velcro on whatever leg...
