. . . In my mind, besides stiffer polymers, or a more equitable weight distribution in the handgun, the best remedy from a design standpoint is an ultra-low bore axis. The Steyr pistols come to mind for that. I really would like to try one someday. And kind of miss the time when they were rather cheap, as low as $299 as they tried to enter the market.
Just as one anecdotal data point . . . a salesman at a sporting goods store mentioned to me that he had a Steyr pistol, and he had sent it back to the factory for repair as the integral lock self-engaged from time to time when he was shooting it.
He was not happy.
