I wouldn't put ANY cast bullets through a Glock.
Working at the local gunrange, I've personally witnessed several of these blow up due to excess lead buildup in the factory barrel. So far, only minor hand injuries have resulted, but the potential for more serious injury is there. Also, sweeping up the debris from the exploded handguns is interesting. Parts seem to scatter over a wide radius. The stunned look on the shooter's faces is priceless.
