Well understand that part due to the fact a few will mess up the fitting it to a frame does happen. I have had a number of extra Colt frames and slides and fitted them with 9/10/40/22tcm/22lr/460 rowland
Have fired them after my 1911a1 dedicated pistol to that caliber really no difference in handling and accuracy. Each to their own I just like to work on guns change barrels and all the other neat stuff that goes with working on them
I have a Ruger SR1911 commander in 9mm. Only a couple of boxes of ammo through it. No malfunctions. Shoots like a dream. Wife wanted a G19 instead, so I am going to sell the Ruger, or consign it at New Frontier by the end of this month.
