Just finished treating my MP45 to a Trigger Job using instructions posted in another thread. It was pretty easy and worked like a charm. I will add that the Sear Housing Block for the 45 is made a little differently than the 9/40.....the striker is a litttle different as well. Now I just need to go fire some live rounds through it before giving the final seal of approval. I'd alredy installed a Burwell polished FP Safety, so I only needed to do a little polish the trigger bar and file/stone/polish the sear. Took my time and didn't remove too much metal. Was able to get the trigger pul down from 7-8 punds to 5lbs......with a nice crisp break, NO OVERTRAVEL and short reset!!!
