I took my Shockwave out the range to shake it down and zero the sight. I learned a few things that I needed to improve.
First, the position I had mounted the InForce light was a no-go. It was mounted at the front of the Magpul fore end on the left side. This makes it easy to thumb the light on and off, but every time I fire the shotgun, the light hammered the end of my thumb under recoil. Ouch! After about 10 shots, I had to take the light off to be able to continue. So, I moved the piece of M-lok rail and the light down to the bottom of the fore end. This is pretty much the same placement of the light on the SureFire DSF fore end. It turns out, I like this a lot better! Not only does it not beat up my thumb, but it is now more in line with he bore of the gun, almost like a sight. The light also no longer throws a big shadow from the barrel. Finally, it acts as a hand stop to keep my support hand from slipping forward under recoil.
The second change I made was to the safety. The safety I had installed had two problems: 1) it was difficult to reach and 2) it kept sliding onto safe under recoil. So, I replaced it with a Z-Wave safety. This one is easier to reach and came with a new bolt, which I'm hoping will stay put better.
The third issue I had was my own fault. On all of the accessories I installed, I trusted the thread locker that was already on the screws that came with the accessories. It turns out that I should have used my own thread locker. Virtually EVERY screw on the gun shot loose at the range! The screws holding the sight mounting plate, the stock adapter, stock, even the sling swivel inserts on the stock adapter! (In fact, the slig swivels inserts fell out and now I have tto see if TacStar will send me some new ones.) I removed and reinstalled every screw and bolt with blue Locktite. It should be nice and tight now!
So here's what she looks like currently:
On the bright side:
Once I got it zeroed in, the Holosun sight works like a charm! Getting on target is quick and easy, shot after shot.
Shooting mini shells with the Opsol Mini Clip was so much fun! Negligible recoil, lower flash, super fast follow-up shots, higher capacity... I wonder if these things are viable for actual SD duty? If they are, they're certainly an attractive option.
Ergonomics: The SB Tactical pistol brace is actually very comfortable to shoot with. When collapsed to it's shortest, the Shockwave is a very handy, maneuverable package. I really like the steep grip angle of the Magpul MOE-K grip.
