Why This Shockwave Wins
The 20 gauge chambering makes this Shockwave significantly more controllable than 12 gauge models while still delivering stopping power. The factory-installed laser gives you instant target acquisition without aftermarket modifications. I’ve tested this against standard Shockwaves on our 100-yard range in Spring, TX – the laser holds zero through hundreds of rounds.
