The manual for a certain HK says the following:

"Use of +P and +P+ ammunition accelerates wear and reduces the service life on the component parts of any pistol, including the P Series pistols, and is not recommended."

My question is, what is the build different between a .357 SIG HK P2000 vs. a 9mm HK P2000 and is the 9mm version somehow weaker?

I get than, if it exists, .357 SIG +P would wear a pistol down more quickly. However, a .357 SIG P2000 and 9mm P2000 look virtually the same. It seems that +P+ 9mm would pose no more wear problems than normal .357 SIG. So is the above warning just something the lawyers put in there or were they too lazy to give a fully qualified answer or is the 9mm version somehow weaker?
 
The recoil spring is light enough to get the gun to cycle with regular 9mm sissy loads. Running +p or +p+ might slam it around a bit. I wouldn't worry too much about it. I would bet that the .40 and .357sig springs got an extra pound or 3 on them.

That explains it. Thanks.
