No more beavertail
Fully encloses marker body; no more possible dirt in gun
Weaknesses:
Internal cocking rod's threading is bad
Review:
The threading on the internal cocking rod that screws into the back of the bolt was threaded poorly. The thread isnt deep enough, so theres too much friction when screwing in. I screws in about half way, and then it gets stuck. It has to screw in deeper because that half of a centimeter difference wont let the sear grab the stricker. I had to take a vice wrench and clamp down on the rod, and another wrench and lightly grab the bolt (carefull not to damage the bolt) and twist the remaining of the thread into the bolt. Its stuck on very tight now. The threads are supposed to use lock tite, but tie so tightly screwed it, I doubt lock tite would be necessary.
I might later consider opening up the slideder and polishing the rod so it would slide smoother.
Also, It would have been nice if it came in glossy black vs flat black... it would have matched my Flash better... but its no biggy.
Conclusion:
Its a great product. I was told that this used to be on older spyders, but was discontinued and replaced with the cocking styles we have today. If this is true, Kingman should have kept it. No more flimsy beavertail, or sharp beavertails that would cut you up. You wont need to screw and unscrew the cocking rod, so once you get it in, you're set... so its just a one time hassle deal. I'm giving it a 9 because of the extra hassle of the threading.
