Questions please on my first “06/24 Bern”

[Joe in Colorado]

Thanks to all of you for your helpful replies. I've learned a lot, thank you. Mark's reply was especially helpful, thank you. Mark-yes-the trigger pull is incredibly light. Were I to try and summarize, of course this pistol served in the Swiss military. At some point the original barrel was swapped out, I think also the front toggle link. Once it was retired the pistol was set up and probably used for target practice as a hobby or sport. These modifications include rework to the sear bar and front sight, the firing pin changed, the action seems set for a light trigger pull. During or after this period the pistol was refinished in a semi-professional way, not without flaws.
By the way, for what it's worth I emailed the importer to ask if this notion may be true, I'll post if I get a reply.
Thanks also for the info on the cold blue...I'll try to post some before-and-after photos...any good ideas on refilling the safety lettering please? Just the right off-white color?
Best Wishes, Joe
