Okay, that's good. It basically means it could be one of a couple things; either the catch is broken, the plunger isn't engaging the catch, or the plunger isn't moving back far enough to catch the catch.

There's a Reddit article from some guys who are having similar problems. They think there may be a manufacturing defect in the catch that prevents the plunger tube from sliding all the way back, which prevents the plunger from engaging the catch. I've seen a similar problem with an Orange Mod Works Rampage replacement catch, which is very similar to the Reta design. I even e-mailed OMW with photos showing the problem.

So if that's what's happening, and I'm pretty sure it is, you need to shave off about 0.5 mm at the red line so that the catch doesn't bump into the plunger tube. Remember to maintain the beveled contour - it's important for the plunger to be able to push it up easily when priming.

Alternatively, you can file off 0.5 mm from the top of the reinforcement ring on the back of the plunger tube so that it slides under the catch easier. That's what I did with my Rampage because the catch was metal. Either way, its' your choice.

Let us know how you make out.
