The COAL of a 5.56 would never fit in a 1911 frame.

Perhaps the .22TCM is a necked down 9X19mm?

I don't know.

Edit: Did some looking around. It is a 5.56 shortened to an approximate .38 super length.

The 22TC is a 223 case shortened to these specs, https://en.wikipedia.org/wiki/.22_TC...:22tcm_prm.jpg

It is loaded to the same OAL as a 45 ACP so it will fit in the 1911 platform. The cartridge is loaded with a 22 caliber 40 grain HP and is capable of exceeding 2000 fps in a 5" 1911. The bullets are flat nosed and are normally loaded in a 22 Hornet.
I just recently discovered this round myself even though it has been out for a couple years or more. The muzzle blast is huge and it is very loud but surprisingly the recoil is like shooting a 22 LR through a 40 ounce pistol, There is very little muzzle rise and the front sights come back on target quickly. The accuracy is also impressive.
Armscor is also developing a conversion kit for s but they made a
22TCMR for that which is a necked down 9mm. I don't know when that may be available.
