Seems like alot of electronics. 2 phones, a garmin, a camera, a spot, headlamp, batteries.

Also I "get" why you want the gun, I have carred my .380 before also, but in reality a small pepper spray would probably be adequate in most cases against humans or animals.

You didn't specify anything about what your food and water consists of but did say it was included in your pack weight. It's easy to carry too much water and heavy food items.

Otherwise there is only so much you can do to cut weight and still be happy with the level of comfort you have. You could lose the tent and get a lighter tarp tent, but you may pay a couple hunderd dollars to save a 16-24oz which may not be worth it.
