I have not had a issue with a ejected hull hitting my wrist. And if it did. I could live with another tiny cut. Why add more bulk or snags to your KSG? As to the extended switch. Depends on how much you switch tubes. There are guys who have issues. I have tried different switches. But go back to the original because i haven't found one that works right yet.
I am working on a wigwag to adapt to the gun to alternate tubes per pump. So far my design is to use the ejector to trigger the switch.
I am just designing it in solidworks for now. Trying to find a good concept.
The biggest issue i have found is the extended switches don't always apply correct pressure to the back of the hull to push it out of way of the feed gate.
The different switches have had inconsistent results during my shootings with them on the KSG. So far. I havent found a perfect one yet.
I believe this is the issues most people who bitch about the KSG have. I have inquired on a few and found the first thing they did in their hype of buying their KSG was rush to buy attachments and accessories and then blame the stock gun for their issues. There are actual differences between gen1-2-3-4 of components and fitment. And if a switch was designed around gen1 it might not work on gen 4 but they are sold just under the concept of KSG. So most dont look at the correct fitment of these items and how they affect function of the mechanics of the weapon.
Honestly. Having a big hard-on to drop 8 rounds and switch tubes and drop 7 in 10 seconds is a fantasy.
Its not a AR15 with a 60 round drum. Its a 8 round 12ga shotgun with the worlds fastest 7 round reload. (Click!) and if you build muscle memory of how to switch without dropping the gun off and pulling away from it. You don't need extra reach for the switch.
The only one so far i have found that has potential is the switch from
But even that one i have issues with. I worked with the owner and gave him info. I think he's got the right path. And he'll keep on it until he finds the best end. But i am going to modify mine (my own choice not saying you have to) to shorten the length of the arm and down size the ball cause of my bear hands. (Yes bear not bare) i have too big of a grip into the system to be comfortable for me to shoot using it. I am also going to tig a bit more mass onto the pusher to drive the hulls into the tube more. And round the ramp to make a smoother transition. I feel the steel he uses is a better choice then the alum used by the others. Its all a matter of thousands of an inch in the breech gate functions between working or jamming. And so far. The factory switch has 750 or so shots with no issues. But of the 4 switches i have bought. This last one has the fewest design flaws.
But. I look at things differently. So my opinion might be different then others.
