My shockwave is for home defense. It will never get hot enough to warrant a shield, if the laser is doing its job,lol. I don’t know how hot it would get just pumping the mag empty. In my living room, if that mag is empty, and the 9 is red hot, then all bets are off. On the other hand, my shockwave has, uh, extra features to allow reloading without touching the barrel…
