Aside from competitive shooters the casual shooter (range once a week shooting (If that) 100 rounds or less) is never going to ware out your pistol.
Glocks and other pistols get stress tested well beyond what we would ever do even a fraction of and report little to no failures.
Most of use baby our guns. Shooting +p or +p+ loads as much as most of us shoot is not going to ware out your gun before your too old to shoot it anymore.
