Yes, that will do it. It's not really a weak grip that will cause the malfunctions, it's a weak wrist.


The pistol is operating on recoil. If you fail to provide a sturdy and consistent "platform" for the pistol to recoil against any pistol can malfunction.


Try hard to keep the muzzle from rising as much as you can when firing and see if that helps.
