These race guns belong to a friend of mine. The one on the right is 9mm while the other one is in .22LR It is built on a STI frame and Tactical Solutions upper that Limcat customized to look like the Razorcat. I got a chance to try out the .22LR racegun. I was shooting a paper target at 7 yards away. I was pulling the trigger as fast as I could and the gun did not move at all. It amazed me how easy it was. I could see the bullet holes appear on the paper while looking through the optic. It is an amazing gun and I have seen him rock the 9mm at USPSA matches. He is pretty fast.
