Yes, it’s a slight gamble to trust a self defense round without function testing. That being said, if you trust your platform and have run multiple brands and types without an issue then you can reduce the risk but not completely erase it.mmmm I’ve always used the function test to make sure it works with my platform vs the terminal ballistics. I would never trust the most wizbang ammo ever made if I didn’t first test it in my firearm. I’ve had Critical Duty hang on the feed ramp before. No go for that sidearm.
