OK OK you all are gonna say... why this again
but I been thinking about this lately.....
Why should one not shoot +P loads on the P99 9mm ??
Afterall the .40S&W has the same recoil spring then the 9mm. Shouldn't that alone indicate that the P99 9mm can handle hot loads ??
Just a thought...any input... and no I don't want this to be a debate over 9mm/.40S&W

Because the manual says not to. j/k

You shouldn't use +P because thousands of owners have had Kabooms. j/k

I am waiting for scientific data on this one (which will never happen so I'll be waiting a long time). It would be cool if JD Powers or Consumer Reports did long term gun tests like they do one cars lol.

The .40 slide does have more mass because the front of it isn't milled at an angle like on the 9mm. That will soften the recoil, although I suspect its a relatively minor difference based on the thickness of the cut.

I can only speculate on the rest but I wonder if the locking lugs on the .40 are beefier? Can a locked breech gun be tweaked to spend longer with the barrel and slide locked together that would in some way result in less pressure and less wear?

Well
I wish I still had my .40S&W to compare the two....

All quality brands of military and police handguns from the eighties to now can handle +p and even +p+ loads.
