Defensive ammo in any weight is usually not a problem and usually just moving up in weight to 124gr or 147gr ammo, even in the same family and price point as the 115gr stuff that is causing problems fixes the issue.
I put some of the blame for these problems on the ammo makers that are turning out weak, under powered ammo.
Edit to add: Most of these issues with the 115gr ammo is limited to the first 200 - 300 rounds through the gun. Usually, after the guns have been shot a bit, they'll handle all the cheap/lightweight stuff just fine. It's just a problem with new/fresh recoil springs.
