I`m looking for a DA revolver [357/38] everything I`ve tried, in the past had to heavy a trigger pull. Which guns lend themselves to trigger jobs.... I`ve had very few revolvers in the past but have decided on maybe a 3 inch barrel. I`d like to have about 5 lb. trigger pull, can this be accomplished? I`m hoping not to spend over $500 for the gun and then the customwork would be extra. What choices do I have?
