WGP hinge trigger
Belsales HP 3-way
Palmer Micro Rock
Price is not unreasonalbe at $15. It does make adjustments easier.
Does not come with instructions or spring and ball bearing.
I purchased a cam adjuster based on the good reviews it received here. However, when I installed it on my hinge trigger, I found that I was not able to get the same amount of adjustment as with the screw adjuster inside the grip. The WGP hinge trigger reduces the amount of travel by shortening the back of the trigger pull. The cam adjuster also reduces the back of the pull. Thus, it performs the same adjustment as the screw found inside the grip frame.
However, while re-timing my maker, I found that I was leaving the cam adjuster on the longest pull and making my adjustments with the screw in the grip. While the cam adjuster is a great idea, it did not give me the degree of control I was accustomed with the screw adjustment. Granted, unscrewing the grip is a little more of a hassle, but for me, the extra adjustment outweighs the extra hassle of opening the grips.
As it does not come with installation instructions, this product would seem to be better suited for people who are more adept at autococker care. However, those individuals would likely prefer the control offered by the trigger adjustment screw and not need the convenience offered by the cam adjuster.
The cam adjuster is not expensive, but it is not a product that I would recommend. The WGP hinge trigger is already adjustable in the same manner as the cam adjuster with a greateer degree of control. The cam adjuster does exaclty what it advertises, but I would suggest saving your money for paint.
