I have just acquired two Thompson Center single shot rifles. One a .22 hornet Encore and one a .223 Contender G2. Both are great rifles but the trigger pull is heavy (about 5-6lb) and thus affects accuracy. Is there such a thing as a kit to reduced the pull or would it be better to take them to a Gunsmith? Is it an easy job (for a gunsmith) and doe's anyone know the approximate price?. I am based in Lancashire, England.
