I'm not a gunsmith but I can follow YouTube as well as the next guy.
I successfully swapped out the trigger on my G19 for a smooth faced one. First time disassembling the frame after 2100 rounds and it wasn't that dirty. Just wiped down everything I could reach with a dry patch. I hope to shoot it tomorrow.
Also swapped out the front sight on my GP100 for a Meprolight tritium dot a couple weeks ago. I haven't shot with it yet either. Both guns are getting closer to perfect.
