I always thought the Blackburn was good too. The last time it was re-adjusted I personally put the locktite on the threads. The engagement was good (as I recall, it's been 4 years since it was reset) and the pull was set for 3.5-4#.

I'm planning on taking it to Africa, so it will have to prove itself to be dead reliable before it goes. Right now I just don't have confidence in this trigger.
