Because the Scorpion runs one hundred percent reliable I was able to get a personal best last night. this was on an indoor range and many of the shots are at very close distances with some at longer distances. I figure open class Shooters and even limited or carry Optics guys are pretty even with PCC in this situation. The only upgrades to my scorpion are hbi Springs and an extended capacity mag from Taylor freelance. Several of the other competitors are A or Master class shooters, while I am unranked. It is also helps that the Scorpion is adaptable for left-handed shooters
