I own a mechtech 1911 conversion.
I use a 1911 "lower"...
I make certain that the BATFE is not in my livingroom when I disassemble the firearm to clean it.
I often will clean more than one 1911 pistol at the same sitting.
It is very frightening to know that I could have a bunch of felonies sitting on my table.
YMMV.
