I'm not sure what the term "sloppiness" means with respect to the hammer trigger interface. If the trigger exhibits take up, or over-travel issues, then the problem you are feeling may be with internals rather than the surfaces on the hammer and trigger, like the trigger bar and/or internal springs for instance.
The new OEM sear should not need to be altered in order for it to work properly with an unaltered hammer. A bit of polishing with crocus cloth
might be needed. Any idea what the actual trigger pull measures now?
In order to re-hab a previously altered or worn sear to restore the factory surface, angle, and profile, you will need to make or purchase a jig. These surfaces cannot be correctly re-profiled without one.
If you desire the very best trigger possible, and you are currently experiencing trigger issues, the best way to solve the problem is to contact Clark Custom, particularly if you are dealing with an older gun that has been shot extensively. They are the the most experienced shop in terms of gunsmithing the model 41, IMO.
