The BHP works fine with NATO spec ammo, and lots of that is loaded to pressures that are the same as SAAMI +P, +P+ (over 37,500 psi).
It will accelerate wear over std pressure SAAMI stuff (less than 35,000 psi).
All the MkIII frames got better heat treat when the 40s came out. You can tell by the fine lines on the bottom of the grip by the magwell. Smooth is the older pre 40 mod frames.
Even a steady diet of +P amo should see about 40-50,000 rounds through the gun.
I've heard of people claiming over a 100,000 with std pressure stuff before you break/wear out a major part (slide/frame/barrel).
