yes if it was a jewell or similar and he is familiar with it.
when you use one of them for a while, a 4 lb trigger is like a safety catch.
the danger comes when someone used to a trigger in lb weight goes to use it without knowing.
my Dakota and m70 both have jewells set at 8 oz, as does my fclass fifle which I shoot a lot.
these triggers are very safe if you drop the rifle, slam the bolt, etc, as they have enough levers to cater for such situations.
like any trigger, pushing them to the min limit of adjustment can reduce safety.
a jewell at 8 oz is WAY safer than a 2 lever factory trigger set at 1 lb.
I have not used my Dakota for years, and took it out to shoot a deer the other day, and it was just like an old friend.
incidentally it is correctly bedded in a brown precision stock, and I had no time to check zero.
BANG, right in the neck where I wanted the shot to get meat.

p.s.
having seen some clients on videos, if I were a professional hunter I would cut up their rifles with a cutoff saw for the safety of the world, and certainly would not let them near an animal.
some of these pros then go on to praise the marksmanship of said client, praising them when they should be berating and belittling them, having wounded something badly.
the pro then goes on the shoot the animal, and then congratulates the client!
and said client knows so little that he believes it!
