....it's always the same comparison of apples and oranges. Hardball ist nonsense-ammunition. Hollow-Points or EMFJ might have made a difference. Caliber most likely wouldn't. Defense-calibers all behave pretty much the same if you compare the same type of ammuntition. The only exeption is the .45 from a 1911, that one jammmmmms
(That's why I would chose a Glock to shoot 45's if....at....all....)
