Sorry, I am late to respond to this post.
My father had the very same gun. He couldn't hit a thing with it. It was shooting right. He took it to his friend the gun smith and he moved the sights and did some trigger work and my Dad was able to hit very accurately while seated and leaning forwards with elbows on knees.
However, standing and shooting a two handed relaxed stance my father was again shooting to the right.
I shot the gun, as did my cousin. We were fairly accurate but not very precise. After a lot of practice we determined that the gun just isn't for my Dad. Sometimes you hand size, hand strength, arthritis, and other factors mean some guns are just not for you, IMO.
My father was able to hit accurately and precisely with another 9mm semi-auto that day and since then he has bought yet another brand and shoots well with it.
His nephew is shooting the Ruger and says the same, accurate, not real precise, but no jams and the price was right.
