I sure do thank you for telling me what folks used to go through!!
I have established the hood notch in the slide is not oversize.
I have decided to just fit a new bbl,probably a Wilson semi-drop in.
I've also decided I can determine how much,if any,steel needs to be removed from the underlugs with a set of gage pins.
Heck,I might even buy a book so I don't have to re-invent the wheel.
Did you know the guy who invented the wheel gets all the credit,but I have to hand it to the guy who decided to radius the corners of of it :-)
