East Bloc primers are always a good test of how robust the ignition is on a striker-fired gun. The Wolf Polyformance caused some issues in the Honor Guard 9.
The Ruger American Compact went through fifty rounds of the Winchester Q4318 124gr NATO ammo without any malfunctions.
I found a tiny torx wrench to tighten the front sight on the Honor Guard 9. It held through the fifty rounds of Wolf Polyformance 115gr. Four rounds took two strikes to ignite, one took three, and one took four. All fed, extracted, and ejected properly.
