Ruger M-77 MK II Hunter Trigger Spring
Installation of this spring will reduce your triggers
weight of pull by 1 to 1½
lbs. with no other changes.
In some cases just the installation
of this spring will be all that is necessary, however some shooters will require less creep, and an even lower weight
of pull, which will be dependant upon the type, and amount of tuning accomplished by your gunsmith.
I sell this spring with the understanding that it is just one necessary portion of a complete trigger job.
None of the standard M-77 MK II based trigger
assemblies have adjustment provisions for weight of pull, or sear engagement.
weight of pull will be determined, in most part, by 4 factors. #1 Sear/Trigger engagement angle. #2 Amount of
this engagement. #3 Surface finish. #4 Weight necessary to compress the trigger spring. Easy acces is only
available to one of these factors. This is the weight of pull spring. After the barreled action has been removed
from the stock, this spring can be replaced with only a pin punch. Replacing this spring is simple, cheap, and a necessary
Picture #2 is of a Power (brand name) trigger stoning fixture. This is the
best way I know of to address the other 3 factors which determine your triggers "feel" and final weight of pull.
You can spend more money, and you can spend more time, but the best value is still obtained by replacing the
original trigger spring, and tuning the original trigger.
IF YOU WANT A LIGHTER TRIGGER PULL, YOU NEED A LIGHTER TRIGGER SPRING!
