Why? Why should I switch calibers because I don't like the ultraconservative, underpowered standards set by SAAMI?
Utraconservative and underpowered as they are these are specs that engineers design guns with and add a significant safety margin.
It's only a 10% increase in pressure, which is hardly anything to write home about. (35,000 to 38,500 psi and the 9mm can handle up to 44,000 psi)
44,000 psi ammo will wear down a gun designed for 35,000 psi ammo faster. You can keep pushing the envelope but it will break at some point.
IMO, non +P 9mm ammo is underpowered. The reason we started adding pressure to the 9mm was to increase terminal ballistic performance from the original standard set in 1902. (Which it did!)
Well how much did we increase the terminal ballistic performance? 50%? No more like maybe 10% in reality. This is not going to win a fight. There are too many other things to be concerned with in looking to win a fight. Most of them are mental and have nothing to do with guns, ammo, or shooting skill. Among them I would place what bullet low on my list after establishing reliability of the ammunition to function.
Too many people get way to wrapped up in what bullet they are using rather than the important stuff.
He said +P has no use to him, I said it has use to me...
No, I said...
Standard pressure ammo should work fine.
I am not a fan of +P or +P+.
I use +P in K frame and larger 38s and +P+ in 357 revolvers. AFAIC semi autos are designed by engineers to operate in a narrower pressure curve due to all the parts that need to cycle.
Edit: And yes, "incredulous" was a very poor choice of word on reflection.

Thanks for recognizing that.
Dr. Roberts has not vetted a single 115gr 9mm round, with the exception the Barnes copper bullet, since they began vetting rounds in terms of ballistic performance.
This is the second time I heard "Dr Roberts" name dropped as if everyone automatically knows who he is (he's a dentist that has done a lot of research in terminal wound ballistics for those who don't know). This leads me to believe that you have drank your share of Dr. Roberts' Kool Aid.
Don't perceive this as an insult as we all partake of somebody's Kool Aid. Just don't get totally wrapped up in what Dr. Roberts says as axiomatic. He spends a lot of his effort (as many do) working at disproving what many of his predecessors have done. I've drank a lot of Kool Aid in my time from different sources but have never finished the glass. Be a bit skeptical of anyone's blanket statements.
After all in conclusion, you say,
But I'll agree with you that they will all likely get the job done, and failure is highly unlikely
and I said,
Standard pressure ammo should work fine.
Which leads to agreement I'd say.
