Most wear comes from the immovable components like the lips on the receiver where the carrier rides. The only resistance the hammer offers is the spring rate of the hammer spring and like Tim said , the disconnector. The hammer is at 90 degrees initially before it even gets to the ramp. When I researched info on the subject, when I did my 9mm conversion, it was said the carrier return spring played very little part when you consider 50 KPSI chamber pressure. The most influence on slowing the carrier is the mass of the carrier, that was why weight had to be added to the carrier for the 9mm conversion because it eliminated the lock and delay. The carrier spring and trigger were unchanged.
