What about a chest holster. Kenai makes a real good one. Well made, lite weight and fits well/flush against your View attachment 203816
X-2Eberlestock Nosegunner. 4in 1911 In the back with full size binos inside.
I used this during archery elk last year. Great idea, however it needs some fine tuning. I am 5'10" and mounted it to the bottom of my AGC bino harness. The razco hung down so low the back of it would sit over the top of my backpack waist belt and makes a fair amount of noise while hiking. While sitting it would dig into my groin/thighs and was uncomfortable. I simply abandoned ship half with it way through the hunt. It was more hassle than what it was worth. If you glued some felt to the back of the holster that would prevent the noise from riding on top of the waist belt. Or, if you are taller than 6 feet it will definitely sit higher. I wouldn't recommend it for someone with no beer belly and shorter than 5'10".connects to bottom of your bino harness.

I carry on my chest or belly....I recently got a Mystery Ranch Sawtooth 45. I'm wondering, how are you all carrying handguns while wearing frame packs? The gun I'm looking to carry is a 1911 10mm 5" barrel. An accessible spare magazine would be nice too. I also wear a bino harness, so that cancels out a chest rig (I think). Thanks in advanced for any help.
