Re "missing four triggers"
Here are 3 statements of highly esteemend gunsmiths who did or still building guns of Boss type incl the Boss single trigger
1. The Boss single trigger has "no expiration" date, like a
car engine, it's a reliable feature.
It may need a new spring, but that's it.
2. Oiling this single trigger is not a DIY exercise.
It should not be kept dry, too much oil sill stick it.
The profi uses thin oil PlUS blowing it out.
3. You will earn a lot of problems if you let restock a gun with this trigger by a stocker who is not familiar with this trigger-specs.
