Hi Dustin, no sir, this will not shoot .45LC, it is chambered for .410 only.
The standard bore diameter of a .410 is as expected 0.410 . Colt is 0.451-.454 inches in diameter. That is significantly larger than the bore of a 410 shotgun it would be unsafe.
Stay safe & have a great day!

NO IT IS UNSAFE TO SHOOT A 45LC in a 410 look at it this way the 410 has a bore diameter of 0.41 inch the 45LC uses a 0.454 bullet trying to push a .454 bullet through a .410 hole will cause a huge spike in pressure which the gun is not made to handle. Guns like the judge can fire a 410 because the bore is made for a 45LC which is larger than 410.

Hi Dustin and welcome. No Sir. Chamber pressures would be too high. So, for safety and warranty reasons, you should not attempt firing .45LC form this shotgun. Cheers, stay safe and enjoy!

You can but it is not advisable. The 45 LC round will fit in the chamber and fire I have seen this done. The problem is that most 410 shotguns are choked full so when the 45 round get to the choke it squeezes the bullet creating a great deal of pressure on the barrel.
