I looked over the post on the bolts, and saw what appears to be a misconception. The top of the "legs" does not ride over the cam when cocking, the BOTTOM of the legs ride over the D-cam, and when the cam rotates, as the cam tapers out, the legs ride over the side of the D-cam and allow the bolt to pop up and complete the locking of the cylinder. The finish of the bottom surface and the tension between the "legs" and the cam and frame are what dictates most of the resistance felt. Properly fit and finished, there should be no difference in them.
Just my two centavos worth.
