If that 9mm chart is correct and Geco is the same and made by RUAG then the info above isn't correct, the Muzzle Energy is not 281 ft.lb but much more: 382 ft.lb

I ordered some Winchester 115 gr to replace my Geco 124 gr but for what I saw in that chart, only the weight of the bullet change, the energy and the velocity are almost the same.

Do you think that with these Winchester 115gr my P08 is more protected to break again or must I use another brand?

thanks

The lighter bullet will develop less pressure for the same velocity.

The INDEP ammo was around 1350 fps for a 115 grain bullet. And I shot plenty of it in my Luger.

Charts values are all very well but...

One important thing. 1930s Mauser made Lugers have stronger recoil springs than the ones from WWI, the ammo was increased in power in the meanwhile.

For your last question. We are using 75 year old plus guns. No one can tell for sure what they went through all those years. So, no guaranties whatsoever.
