Buy a book titled The ABC’s Of Reloading, by Dean Grinnell.
And digest it, thoroughly. It won’t steer you wrong.
I have had seen replacement spring sets fire thousands of rounds without a misfire or hang fire in Ruger revolvers. Do you want the gun for enjoyment? Then a spring set and shooting 38 SPL ammo works well. If this is a personal defense gun you may want to keep it original, you’re not trying to take an inch off your group at twenty five yards. The original springs, are easy to swap out if you have them.
Thx for recommendation.
