Congrats on getting your new rifle.
As mentioned earlier, I've dinked about with Ruger No.1's and No.3's for more than a few years. The initial issue you describe is quite typical for a No.1 fresh from the factory or an unworked gun. The rifle will never reach its full potential until work is done to both the lawyer trigger AND the forearm issue.
Here's a link to get you started. For the record, virtually every No.1 or 3 I've known has responded favorably to these mods. Without them, the rifle will always be regulated to "so-so" accuracy. With the mods, it will shoot right alongside a good bolt gun; mine does.

If you are not mechanically inclined, or not familiar with working on rifles, give it to a good smith that specializes on these rifles, and there's quite a few that do. These guns are fully capable of shooting 1/4" and less at 100 yards, but not until the inherient factory flaws are corrected. Good luck, let us know how she shoots once the usual No.1 issues have been resolved.
