I know there's allot of opinions out there but... I'm looking at getting a 617 but am really struggling with which barrel length to get. This will be a target gun for the most part so I lean toward the 6" but read allot of folks have issues with the weight distribution of the longer barrel and say the 4" balance is better..... ????? Many with both say they seem to leave the 6" home more than the 4" and just like it better so I find myself confused on the issue. Would love some help in deciding.
