Not sure what the standard load was in WW2 as there were multiple loads in 9mm using light to heavy bullets manufactured. The original military load in 1908 when the Luger was adopted by the Imperial German Army was 123 grains at roughly 1090 fps.

Bullet weight and velocity are only two factors to consider. The powder used makes a huge difference. The powder must provide the proper impulse without excessive pressures and a medium burning powder is probably the best choice. Slow powders can maintain high pressures for too long and cause damage such as your broken toggle.

Most people find that Winchester 115 grain white box cartridges work the Luger action well. Be cautioned that heavy loads and NATO spec cartridges are a really bad idea for the Luger.
