Hands-on usually is the best training; and it sounds like you're getting your share of that with this project. Good show, and keep at it.
You've done better already then when I bought a Wolff gunspring pack to do a trigger job on my revolver (a Ruger SP101). I have a pretty detailed guide and schematics for this work, but
it was complicated. I also noticed I probably didn't have all or the best tools to move ahead. Instead, I decided
not to dis-assemble my revolver and had a qualified gunsmith do the work. I suspect that "needing more experience" is exactly where I would have been if I attempted it myself.
After going through the 30 dis-assembly steps in the printed trigger job guide (which also meant no less than 30 re-assembly steps), I came across the clincher that moved me to bail out of the project. The author of the guide published this warning to the reader:
Warning
An improper trigger job can render a revolver useless or result in a dangerous malfunction. Several parts in the revolver are carefully fitted at the factory. Any significant changes to these parts can make the trigger pull worse or render the revolver useless.
I let my imagination run a little wild with the warning for just a very few moments. That's about how long it took me to "bail out!"
I'm certain my revolver would have become an "instructional tool" similar to what you are now working with, CT-Shooter. But like I said --- Good show! You're going after it, and will definitely profit from the gunsmith training.
Looking forward to your final report, and also your next HRR Range Report!
Take good care.
I'm certain you do feel very pleased with this successful outcome of a fully-working HRR! Good job
