Or put sideways pressure on them, especially when transporting them in soft cases in overpacked cars. Unlike most here, I don't think for a second tang cracks come from straight-back pressure. Look at the gun. Bad design on the cheeks and tang. Sideways pressure is what cracks them. If it was recoil, the heavier guns would crack more often than the 22 hi powers, 303's and 250's, but that is not the case. They all crack the same.
