I constructed a new SNAP variant today in an attempt to use the Suicide Trigger with a 360 degree catch notch (similar to Carbon’s Mk II design) but it seems that the plastic couldn’t stand up to repeated abuse from the metal catch pin despite my best efforts to smooth it out.  Pictured at right is the catch notch on the plunger rod after about a solid day’s worth of use.  It actually hasn’t failed yet, and works fine in this state, but I doubt it would last much longer in this condition.  I was successful in making a solid, stable handle with a smaller footprint for use with a sleeve-style pump action.  More photos after the break.

Update – 1/5/11 – Photos of the new proof of concept at the bottom of this post.

I’ve been trying to put together a catch mechanism that can sit behind the spring, like the rainbow, so that I can make a pumpsnap where the pump doesn’t have to stick out in front of the gun. I had some ideas about using a 1/2″ flat endcap as a catch plate, but a post from PVC Arsenal 17 got me thinking about using a simple clothespin trigger on the plunger rod itself, and just using narrower pipe behind the spring to eliminate the space in between, to prevent the pin from being able to wiggle free. What I came up with is surprisingly simple.
