Re: Full lenght guide rod, pros/cons?
I agree the Group Gripper is a completely different animal. But if a person were considering a full length guide (I don't know why as it does no good, in my experience) the Group Gripper is a much better choice and actually does something if you include the fitted barrel bush. And it is not the fitted bush that makes for the better performance, as I installed that first with little improvement.
For the money the combo of a fitted bush and the Group Gripper I think gets you the most accuracy bang for the buck. It flat works.
