What is stopping power? It is a artificial concept. The only knocks on 9mm would be its ability to penetrate barriers and it's smaller size which creates a slightly smaller permanent wound cavity. 9mm rounds are VERY capable of achieving adequate penetration.
Not only does the RCMP use 9mm but they conducted extensive ballistics tests comparing .38, 9mm, and .40 before choosing the 9mm.
But are we talking hardball ammo here or are we talking LEO rounds like Hydra Shock or the like, which in essence are jacketed hollow point. The rounds used by the armed forces of the 'civilized' world must use hardball ammo and so a larger, faster moving round is a good thing... whereas, the local police can use whatever they want pretty much including frangible ammo, which will indeed penetrate, create a larger permanent along with a larger temprary wound cavity (causing greater trauma) and then cover up its tracks, likely without exiting. The latter rounds will have greater "stopping power" IMHO. Common sense.
This debate runs regularly on the various boards and all of the usual documentary evidence is provided.
For my money, if I am depending on a specific round to protect my LIFE... it's going to probably be a .45 jacketed hollow point of specific design for self defence. The ammo you use for the range is just that... ammo you use for the range.
Be sure about what you are loading and the purpose therefore. And the legality thereof.
For the physicists among us, jacketed hollow point, especially the self defence hi tech rounds, slow down and stop a whole lot faster than hardball ammo mandated by NATO. The end result is a much higher transfer of kinetic energy to the recipient... and a larger "ouch" factor, resulting in "hey, I've been hit". I can recall discussions with various LEO's where someone has been shot with a 9mm and has not been slowed down initially. Change this scenario to a long gun round with greater muzzle velocity and kinetic energy and a target strike has huge impact. There is no "hey I've been hit" notification to the brain as they are splattered all over the place.
Again, there are many reports online to read and education oneself and there are many contradictions to said reports to give one food for thought. For my bucks though, it's going to be a .45 with a LEO round in it. There are many wee guns that will double stack ten rounds inside the waistband for self defence and well concealed. (USA only or LEO of course - do not go breaking the laws of the land please).
