In good order the Jones screw grip works very smoothly. I use them a lot. If you get one that is functioning correctly, it will last a long time before going out of order.

Like most mechanisms, one that has been badly repaired will be harder to put right.

I'm lucky that I have the best welder on the planet and he lives around the corner from my finisher. Together, they have sorted out a few of these for me over the years. I'm still shooting one as my 'go-to' gun. I like them.
