Get some coated bullets from Bayou Bullets. They smoke less and leave no lead in the barrel. There are a lot of makers of coated bullets these days. They cost about the same as lead but are a lot cheaper than jacketed.

I was pushing 9mm coated through my 929 and had no need to run a brush through the gun after 1000 rounds. No leading is nice. Also the cylinders stayed clean and didn't need to be scrubed as often.
