Best trigger pull of all my BHP's!

I installed this kit in a new Girsan MC P35 OPS. The factory trigger pull was so horrendous it could not be measured. In excess of 20lbs. The sear and hammer engagement surfaces polished, but the angles were uneven and terrible. To call the difference between the factory hammer/sear/springs and the Cylinder & Slide replacement, night and day would be a disservice to C&S. This gun now has the best trigger over every other BHP I have owned or currently own, by a wide margin.

Awesome

I purchased the C&S hammer and sear separately on sale, and used a Wolf 26lb hammer spring. I may have just been lucky, but installation was straightforward with no modifications needed for proper safety function. This along with mag safety removed resulted in a very nice, crisp, 4lb trigger with no creep. (Restored Hi-power alloy frame, range queen.)
