A Glock will handle +P rounds with no problems. I have a G20SF 10mm and shoot the Buffalo Bore +P+ ammo with no issues.

My normal carry gun is a 1911. I carry the Winchester PDX1 230 grain in them because they are at the top of the standard range for energy and work well in all of my 1911s. Shooting a steady diet of very hot +P in a 1911, can cause premature wear, cracked frames, and cracked slides.
