Inspired by Rhett @RustyCrusty, I bought a Shockwave S at the 11th hour before Oregon’s horrific gun and mag ban was to go into effect. I wanted a compact truck and camp gun to replace my AR pistol. (What do we think about AR w/10 rd mags vs a shotgun?)
While the cheekweld grip works well for me with an AR, I didn't like it with the Shockwave. There's no doubt this can work really well--just look at Rhett's videos. But I found the hand position really awkward. Instead, I discovered it shoots ‘shockingly’ well with the grip at midline on my chest. This required a tall 1.93" optic mount. (Note the wrap with a bit of foam under it to soften the blow.) Parts list to follow.
