If you enjoy a small laugh, here's the blurb on the "Huber Concepts" Krag trigger -

30-40 Krag-Jorgensen Trigger

The 30/40 Krag proved its effectiveness in the hands of the Marines of Teddy Roosevelt’s “Rough Riders” at San Juan Hill. Originally of Danish/Norwegian design, with a side load magazine. Huber’s Triggers with patented ball bearing technology provides better timing aspect in shot delivery sequence. Provides adjustability’s for creep, set, and over travel. The 30/40 Krag is only available in black Teflon finish. Typical short duration break weight at 2-3# on drop in, and replaces the trigger component only. Minor wood relief may be required.
