Ok guys I am looking at getting a Dan Wesson Vbob and I am thinking about breaking it in with the NATO specd 124 grain so is it gtg?
NATO spec 9mm is a +P load, but for some reason Winchester doesn't plainly state this on the box.
It's not weak stuff, it's just cheap.
Anything over max SAAMI pressure is overpressure and thus should be considered +P, even though it doesn't reach max pressures that SAAMI specifies for 9mm +P.probably because it isn't plus P - only about halfway between standard and plus P

It's the same dimensions as .45 ACP, but the case is thicker to prevent ruptures from the higher pressures. The headstamp is the biggest reason tho, it's a red flag saying "DO NOT SHOOT IN A .45 ACP." Winchester 9mm NATO doesn't say that.I think the reason it isn't marked +P is because 9x19mm NATO is considered a separate cartridge from 9mm Luger in actuality. Isn't this why .45 Super is marked as such and not marked with a +P even though it essentially is the same cartridge as .45ACP?
I find it so odd that ammo makers will pump out weak loads forever because one gun made decades ago couldn't handle the full power of a cartridge and it's a safety issue, but a company like Winchester doesn't think to themselves, "Hey, what if someone shot the higher pressure NATO ammo in a Luger?"
I believe such a round would likely break the gun, but I can't see even an original Luger having a full on kb from 9x19 NATO.
According to my googlefu, 9x19 NATO chamber pressure is listed as 36,500 psi. 9x19 Luger is 35,000 psi. and the proof loads used in European countries generate 44,000 psi.
From an old post by Luger_carbine:NATO spec 9mm is a +P load, but for some reason Winchester doesn't plainly state this on the box.

9mm standard max pressure is 35,001 psi
124gr 9mm NATO max pressure is 36,500 psi
9mm +P max pressure is 38,500 psi
