I put a Volquartzen trigger kit in my 22/45 a few years ago. It started off at around 2.5 pounds. After a couple thousand rounds, it's now settled in at around 2 pounds. It's perfectly safe, but be forewarned. When I shoot a few mags in a pistol with say a 5 pound trigger, then pick up the 22/45, the first couple shots are interesting until I adapt to it.
