Thinking of upgrading to an Anschutz 1827. Wondering what the difference is
between the
models. Regular vs. Sprint and the different barrel types - regular, stainless,
nitride, etc.
Would there be any noticable difference between the models?

Also how does one dryfire the Anschutz 1827? I see there is some kind of dryfire
adapter
available. Does this need to be inserted before any dryfiring session and is it
easy to do?
