Completely understandable. Not every part will be 100% drop in and will need some sort of fitting. I'm not too worried about the sear springs, I can always file down the width to make it fit, I just didn't want to do it then. But to be completely honest I like the EE kit a lot better (YMMV). The crisp, glass break of the sear/hammer paired with the super light hammer is different than the HD and EGW kit. With the hammer being designed the way it is, it has a nice sound to it too!It dropped right in on 2 of them the 3rd took a bit of finishing. However i always polish new parts before even installing them to avoid possible problems down the road. If it had burrs it was gone after some light polish and never noticed.
Apologies for not being much help in that dept.
