Many 9x19 pistols will shoot very poorly with leadbullets as teh rifleing twist is wrong for lead.
The old standard twist was around 1-10 and the twist used by smith in their revolvers and matchbarrel producers is normally around 1-16.
SO dont expect to much out of your gun with lead.
I have shoot a bit of lead, but i am using a custombarrel with the right rifleing.
