Adjusting,the sear spring can change the pull that much.no parts needed that way.

any smith that works on 1911 style pistols should be able to do it without a problem.just be sure all the safety features still work correctly after the adjustment.I just put a new sear spring in mine and adjusted it myself,all you do is slightly bend the spring.if you do a search there are some photos and instructions on how to do it,however to be on the safe side you may want to have a smith do it if you're not comfortable disassembling your pistol.
