The reason they are no legal in CA is because they cannot pass a drop test with a round in the chamber...or Colt didn’t submit them for safety certification.
It’s got nothing to do with an AWB. They ban these guns under the color of safety.
“...or Colt didn’t submit them for safety certification.”
Likely didn’t submit it. It is tested to destruction and not returned. On low production run items, it isn’t worth the headache. So California just doesn’t get all guns. Even a minor change such as finish or sights means a whole test for that and only that gun.
It isn’t “Colt 1911 .45”, It’s every single thing in the catalogue if they want to sell those things.
