I had a chance to fire the Shockwave with the heat shield today. The heat shield did not move at all. I fired 15 rounds of slugs and then 5 rounds of Federal 4 Buck (27 pellets) within just a few minutes. Again, the heat shield did not move. Not even a little bit. I used a coating of blue loktite under the front mounting band of the heat shield and tightened the mounting screws very tightly. I did not fire the gun without the loktite but I just went ahead and coated the mounting band. It looks like I won't need to drill and tap the barrel which I only would do if absolutely needed. The shield was just a little warm after the 20 rounds and the barrel was hot. I had fired a few rounds of 00 buck and 4 buck just before when I patterned the rounds. I'll post some photos in a day or so.
Sorry no photos, but I picked up my shockwave marine coat yesterday and took it straight to the range. Wow is this thing fun. I was suspect about the grip angle, but it worked as advertised. Mostly was shooting #6 shot, which was a breeze. A few rounds of OO buckshot had more recoil, but not much more. I have to say this "firearm" is very well designed. I'll get pictures when I can, but if your wondering about this particular model I give it a thumbs up!
Shot a couple of boxes of #2 and 6 shot. No problems; shield stayed where it was supposed to be (no movement whatsoever.). I'm satisfied. Maybe not too pretty, but neither am I, so......
Us Shockwave fans are happy for you. It's a fun weapon, yet it fills a special place in personal defense.Finally, got me one!
I never thought I'd see the day you could legally buy a short barrel shotgun without a tax stamp and six month wait!
