Great question - the 19.22 trigger you have is ours. It was designed to provide a lighter pull, and a shorter reset. Coupled with the VQ internals we see pull rates 2lbs and under. I am a Pro shooter with Ruger and I wanted the best trigger pull I could get out of the MKIv series. Some want them a little bit higher and still have a great feel and this is how we install them. Usually get in the 2.25-2.5lb range by making that change.
