A San Francisco police officer, during a foot chase with 28-year-old Oliver Barcenas, the gang member and felon, pulled out a modified pistol with an exceptionally long magazine. Upon noticing that gun the officer pulled his sidearm and fired, striking the man in the back and critically wounding him. (On the video you can hear the officer tell other officers that they had to find the gun and it looked like a Tech-9.) Minutes later they did find said gun (see the picture) right where the officer saw it in the hands of the felon.
