Isn't it just super cool!! The RO/Instructor/Gunsmith that introduced me to it put his on about 20 years ago.I installed an SFS on my primary ccw, it’s a S&W scandium, it’s super light for all day carry. But it’s my favorite 1911 becouse of the safe fast shooting system!!!
He told me that there were manufacturers that had started installing it on production 1911's but it jacked up
the price by about $200 and buyers wouldn't pay it so they stopped.
