I personally feel that the +P and +P+ ammo is more marketing than helpful. Let's be honest here, how often does the higher pressure ammo really help the common man or woman who buys them "just because". In the real world, how much difference does +P ammo make in a real SD use? Can anyone really say that a life was saved because +P ammo was used instead of target ammo? Yes, HP vs. FMJ ammo does help over penetration but when we talk speed, does it really help? I feel it may hurt the casual SD shooter because follow up shots may suffer. +P ammo is not that big of difference in a real SD situation. It's all hype.
Yes, those who post here know why there is high performance SD ammo and what it does but when I read chrony results and see a 100fps difference I really ask myself if in a true SD situation, does it matter enough to say the difference is what saved my back side? No. We treat a true SD situation like we are Spec Ops with the best advantage we can have when the truth is when you present your firearm, most of the time the offender pees himself and runs away. If you shoot at him, he doesn't know you are using +P super performance ammo. If you hit what you aim at as fast as you can pull the trigger, +P ammo means nothing. It's just like a horsepower war with typical street cars. It's all show, marketing and taking our money for perceived greatness. It's all about the talk, not the end result.
