P320 Carry 45, 9MM, 357 Sig, Colt 1911, QHMC M1 Carbine, Astra 1915 32, Mossberg MVP Patrol 5.56MM
Perhaps those more knowledgeable can help me understanding something: I keep reading that modern bullet technology has brought the 9MM up to the level of larger/more powerful calibers (357 sig, 40, 45) - that there is much less difference in performance between these calibers than there used to be. However isn't that same modern bullet technology available in the larger calibers too? If so, then wouldn't the difference in performance between 9MM and the larger calibers be maintained? Or, does the modern bullet technology raise the performance of 9MM to a greater extent than it does for larger calibers? I haven't seen that question addressed (though I haven't looked that hard). Does anyone know, or have a perspective on this? Thanks.
