Gun blogger Linoge (Walls Of The City) was testing the USFA ZIP Pistol when it suffered from an out-of-battery discharge …
Immediately on pulling the trigger on the 27th Golden Bullet round, I was confronted with a bright, actinic purple flash from the ejection port and magazine well of the ZiP, the magazine was forcibly ejected from the firearm, my hand and face were peppered with some manner of debris, and my right hand felt like it caught a baseball bat mid-swing. I basically threw the firearm on the range bench and backed away quickly.
Ouch! Lots more photos and the full report here.
