What is the best break-in process for a tight 1911? Is use of a lapping compound ok for slide rails, and barrel / slide fit-up? ........thanx........

Save some money and cycle the slide by hand with or without the recoil spring. Then shoot it.
Lube and shoot. You don't want galling or a chance of locking up. It will wear in soon enough.What about this for a plan.......clean all the contact points w/ solvent, and then cycle it dry by hand or firing. Wouldn't that expedite the break-in ?
Absolutely true!!! Lapping compound will make the slide easier to rack....and it will also ruin a nice slide to frame fit. Lapping compound removes metal. A non-imbedding compound like J&Bs is not a safe solution. It still removes metal, it just doesn't imbed itself in the metal. So they say. I have fit my share of slides to frames. And don't even THINK about using a few drops of cutting oil to smooth things up. Worse than lapping.No lapping compound

Better to just shoot it lubed.What about this for a plan.......clean all the contact points w/ solvent, and then cycle it dry by hand or firing. Wouldn't that expedite the break-in ?
Well, I tried it once and it loosened up my fit. Les blew up when he found out and took a bite out of my medial posterior superstructure. I never did that again. I didn't know that there is no abrasive in cutting oil but there must be something in it. Like I have said, I am no machinist.Hmmmmmm...... What exactly do you think cutting oil is? Agreed that it is not a lube, but it is not abrasive either.
I am a machinist and have been for 20 or so years. Cutting oils are all made a bit different. Most are a cocktail of chemicals with a petroleum based carrier. They are made to increase the shear factor of the metal. Taps tend to cut more smoothly. I would say it would make it wear in much faster. But a high likely hood of overwearing or possibly even galling. Never mind if the pores of the gun metal open up from heat and it gets trapped in the steal. You may well not get it to stop the high wear. Sounds like a way to junk a gun.Well, I tried it once and it loosened up my fit.
