Often,, many folks never have any issues. However,, I have been able to purchase 2 Rugers that the owners were willing to sell cheaply because the action "hung up" occasionally. Both were due to unhooked & bent trigger return springs. One was a nice 357 Maxi,, for $275.00, in the box. When taken apart,, the leg that was off the post,,was hanging up in the mainspring.
If a lighter or better action is desired,, a good action job is MUCH better than a poor man's trigger job IN MY OPINION. And,, it's not super expensive to have a qualified gunsmith to do one. Heck,, just a gentle cleaning of mating surfaces in an action to smooth up any rough spots will make a big difference. Than you can add a Wolff spring for the return spring & it too can help.
