Model 27 parts interchange......

I just bought a Pre 27 that has had the trigger and hammer blued. I've got a line on a 27-2 trigger and hammer. Will they fit?

Yes. As long as your pre-27 is a post-war short action, it will fit. With any luck, if the hammer and trigger were an original matched set, then they might drop right in without any further fitting.

That's correct. A matched hammer and trigger set will often be a drop-in fit.

I installed a target hammer and trigger from an M27-2 in my pre-M27 and it timed perfectly.
