IPASS stands for iron plate action speed shooting it has its origins in USA. In essance quick draw shooting. Slugger is that a rifle or a pistol ? Today was my first shoot with my new pistol and it realy is a cracker I dont have a holster yet but just in the garden pretending to draw the pistol I do 5 targets in 4.8 seconds didnt take long to zero my holo sight in its been a fun afternoon. Dose that intrest you. My brother in law will join in, he use my pistol till he gets his own one. You can see some speed shooting on youtube the Japanise have really taken it to the next level
