I bought a 65-3 used and it acted the same way.
My gunsmith adjusted it back to factory specs and it's perfect now.
Personally I'd take it to a gunsmith.
It's like a $25 adjustment.
And if it'd s carry gun it's nice to have it perfect.
Might consider having a trigger job while it's being adjusted.
Smith triggers are good out of box.
But with a trigger job they are the sweetest thing.
