No worries, you likely won't experience problems.
From what I've seen the polygonal barrel 'scare' isnt much to worry about. If you push lead past 1000 fps you'll get barrel leading no matter what the profile/rifling is. So lead is good in .45 and maybe .40 but in full power 9mm you'll have problems.
Some of the experienced shooters I know have used a lot of lead in polygonal 9mm barrels. Generally performance is poor but in some barrels it can work (peters-stahl 9mm polygonal).
Plated & jacketed, are generally good to go.

I can't speak for other guns, but the Tanfoglio's LOVE copper plated and thin jacketed bullets.. they perform better then with the thicker jackets..
