My G35 has about half the number of rounds as my G22 (about 800 through the 35 vs over 1700 in the 22). Yet the finish on the G35 feed ramp already has a little strip worn away, while my G22 is showing almost no wear. Is this just a difference in the finish, or is there something causing an abnormal amount of wear on my G35? Also, the wear on the 35 feed ramp is not dead center, but rather off to the left a little. Is this normal?
