If he is a competent gunsmith get it done. I had the same trouble with my 77 MK II 300 win mag. It had alot of creep and I was going to buy an adjustable trigger for it. The owner of the gunshop where I had been doing most of my shopping is also a gunsmith and he showed me a 7mm mag ruger that he just did a trigger job on. I had my 300 there the next day and he did the trigger work on it. This gun shot good to begin with but I didn't like the creep. Now it shoots fantastic. My opinion GET IT DONE.
