@Jerzy beat me to it. I still have a few things left to document on the enhancements to my RIA but it is rapidly coming to the point where there is little left to improve. I just haven’t had the time to go through the internals to my normal degree of intimacy. I have some fit and finishing work to do, I may have jumped the gun on getting the lower coated as I didn’t do my ramp and throat job before hand but that may be a good thing. The mag well step is an ooops as it has been 20 years since I did a full on custom build and I forgot. I need to give the hammer a hair cut but I want to swap parts inside to see if I can UP the trigger pull before I determine that i have to replace it.
When doing custom modifications one should always have an eye on what effects what as that is the time wen things get spendy or uncomfortable.
Ultimately I will have the slide and all the external bits sent to DOA for a coat of Carbon Black and forward serrations but I need to check clearances and such on the moving parts to ensure I don’t screw anything up finish wise. As with most of my guns I will make it pretty and perfect ONCE. Then I will treat it like a red headed step child and beat the He!! out of it until or if it fails and go from there.
