Could be, but, with 30+ big bore hunting rifles, aged almost 69, and some Timneys in some of my rifles, I am not about to change it now.
I might build on another factory polished receiver ZG action I have and it would be a STS barreled 9.3, but, I will get a Dressels trigger for this if I do it.
Each to his own, yours is a nice rifle, for sure!
