Good Day My question relates to the 357sig vs the 9mm. Now please understand I am not looking for a Caliber war,just some expert claification. A 357 sig is a 9mm bullet being pushed by powder in a case that is the size of the .40 cal. SO WHAT WE HAVE here is a 9mm bullet being pushed with the powder that pusges a 40cal (does this make sense)Would it make sense that the 357 is superior to the 9mm? in other threads some GT members push the 9mm as a round that is equal to the 357 and with +P 9mm rounds it may even be better. I just think that if you look at the 357sig and whay it was developed it would be easy to understand why this round is superior to the 9mm. Your thoughts?? Thanks 1SG Out Wanna kill these ads?
