[QUOTE=Nevada Ed;139474235Ah;
you might add a very short case, also !!
Are we having fun yet ?[/QUOTE]
Yep capacity of the case..larger than normal weight of bullets and the fact that the 9 runs right at the top end of pressures is why I think the probability of getting the 9mm to equal the 45 is almost nil. Make the 9 better than normal??..probably with a lot of work and load development. But then do half the work with the 45 and make it better than the standard 45 too. If you could find a bullet for the 9mm that would reliably expand no matter what weight it would make the caliber a better defense round. That is why I like the 147 Hydra shock and in most guns(up to about 10 inch bbls) it is subsonic and can be suppressed. Oh I forgot...I also have a Contender 9mm 10 inch barrel.. Surprisingly accurate too. Haven't shot it in years
