Yes... more contact, more stability, more durability = more better.Jason, you shooting for all three lugs in contact or will two suffice or is it whatever it will give you for a given gun? If you can get two or three lugs in contact from the start of the barrel fit does that reduce the slight amount of headspace increase you get as the round counts climbs? Seems I remember another smith saying that once the 3rd lug contacts the headspace wont' advance any after that.
My calculations say that with 10 rapid succession rounds fired the heat transfer from barrel to slide to sight will generate enough thermal expansion to bring the thickness to exactly .110 +/- .00001Photo of the day... sight work on the current Colt “Classic” project gun.
Rear of frame and slide is blended, rear sight dovetail machining, and narrowing the front sight to .110”... which I almost got perfect.
