A short video clip from a recent episode of Guns&Ammo TV where the hosts dismiss anyone who claims that the SERPA design is unsafe as "not being able to internalize keeping their finger straight and off if the trigger" or "don't understand the four safety rules".
Whelp, watch what happens when we slow down Pat Sweeney's draw from the SERPA with his Walther PPQ....
