OK here goes. All got weighed with their respective optic, which in 3 cases was a Holosun 510, other one is a PA 1X 9mm reticle prism.
Heaviest: Draco 9S, 8lbs 11oz loaded, 7lbs 9oz dry. Half that weight is the 10" barrel. 35rd mag.

Next: Colt mag AR9, 6lbs 15oz loaded, 5lbs 11oz dry. 4" barrel. 32rd mag. This will lose or gain a little when I find a Tailhook for it.

Lightest was the BCA bufferless running an Endomag, probably because the bolt weighs sod all and it's a 3" barrel. 6lbs 10oz loaded, 5lbs 7oz dry. I weighed it with the 510 optic on, but it's keeping the irons until I can afford another 510 for it! 30rd mag.

I didn't swap the Colt magwell around because it won't work in any of the other pistols due to non-standard magwell or bolt incompatibility.
Couldn't weigh the Glock mag Draco because I already traded it for a Tisas 1911 and mags/ammo.
And that's my Ted talk.
