Well, I've been wanting a GP100 for a few years and I finally got one. It was made in 1993. It appears to have been unaltered and not abused.
I first learned how to disassemble it. I made a Ruger popper out of a piece of short cleaning rod and bought a special bit from brownells to remove the extractor.
I carefully polished some of the internals, most notably the hammer strut and the trigger return spring channel. Nice and smooth, think I'll leave the factory springs. I changed the white outline rear sight and bought a black front sight to have the option over the red insert.
I've been working on some loads, with a borrowed RCBS 38-150-SWC. I have purchased my own and will continue both 38 and 357 load development. I also have a Lee 358-140-SWC that I'm working with.
I'll see about getting some pics in a few days.
Thanks for listening.
