Fascinating.
I definitely need to test some 1911s, if only to debunk all the "my X trigger feels just like a 1911" people. But, none of my 1911s have rails to securely mount them to my rig. I may get one of those railed grip adapters, but I'd rather talk someone into letting me "borrow" their Nighthawk or STI. I'm gonna bring my rig to my next match and offer trigger testing to any of the shooters who want to stay late. Lots of 2011s and raced out CZs there.
