I have a very clean FEG Hi-Power clone, that I bought used.
He had the Cylinder and Slide Hammer and trigger installed while he owned it. It has the very best trigger I have ever felt on a Hi-Power...I've owned 4.
The trigger breaks like a glass rod, with no creep, and a positive reset. But the best part is the hammer; While it appears as a standard Ring hammer from Browning, it must be shorter, as I have a high grip on the Hi-Power, and have yet to be bitten.
The original owner had C&S Novak sights installed. No tritium, just black metal goodness.....this gun is like a laser!
It had a set of Herret palmswell cocobolo grips when I received it. but purchased a set of Philippine mahogany grips form Brownell's. They come unfinished, so 4 applications of Tung oil really made them beauties!
Long story short, if you are on the fence, go with C&S. they do awesome work, and the hammer/trigger combo are what dreams are made of.
