I just installed a C&S hammer and sear kit in my CD HP and what a difference it makes! The original trigger pull was a bit heavy and stiff - my Browning HP was worse - and it had a potentially disasterous problem. If you pulled the trigger when the safety was on and then lowered the safety, the hammer would drop to the half cock notch. The CS parts have cured both problems. The trigger pull is both lighter and crisper and the hammer no longer falls. The trigger pull is especially nice considering I couldn't figure out how to replace the hammer spring with the CS item. The bad thing is that the "no-bite" hammer nips me but since I'm sending it to EGW to have a beavertail welded on, I'm not worried too much.
