My 1911SC will outshoot me any day of the week. I am the weakest link in this partnership. I would not spend my money on the bushing upgrade. Better to spend the cash on more ammo
FYI, I am well over 1000 rounds through my 1911SC. It has been my most reliable 1911 (even over Les Baers, Ed Browns, Kimbers and S&W PC 1911s).
