When deciding to go against the main stream, IE make use of a "unicorn", it should be approached with caution and validation. I put a lot of rounds, including premium carry ammo, and including weak limp wrist / awkward grip testing. I haven't been able to make it fail. Not that you shouldn't do that with every eligible defensive handgun, but with something like Glock, Beretta, etc, you're staring with a baseline.
