I am not too sure on the accuracy of this information as when I was shooting IPSC in Ontario, my buddy was shooting a Glock 22 and he ONLY used Wolf hard cast lead bullets. He shoots about 10-12 thousand rounds a year and he has never had any issues.That's a bad idea....you can get an over pressure issue real quick. Lead bullets need rifling not polygonal rifling. I see your point but it's dangerous an extra cost to put a good rifles barrel on which makes to me a gen 5 more attractive then a gen 4.
