I've been looking into reloading and it seems as though lead bullets are the cheapest way to go. I've got a few questions that I can't seem to find an answer to. The gun in question is a 9mm sigma.

-Will the lead require excessive cleaning?
-Are lead bullets bad for the sigma in any way? Barrel?
-Can I shoot FMJ after lead?

The reason I ask is that this is the only handgun I have and will be my daily carry gun. I usually clean my gun after every trip to the range but I want to know if using lead bullets will lead to a long drawn out cleaning process.

Thanks in advance for your help!
