KWA KP45 (Non-NS2) worth fixing?

[Schuyler]

So, long time since I've posted here lol. Sort of fell off the airsoft bandwagon for a while. I'm trying to fix up a GBB I had a while back. KWA KP45. The one with like a 1/4" of the slide painted orange, no external tip/threaded barrel. Last time I fired it, the slide return assembly decided to snap in half. Below is a diagram of what it needs. Recently reformatted, so instead of a nice photoshop drawing, you get MSPaint! Red is where it broke, green signifies the parts I can find at the moment (it's been a few years :X), but mind you it is broken in half at the red mark. Although JBWeld might be able to work some magic... $30 from KWA for the entire assembly, + Shipping. Also, the magazine I have leaks. So that would need to be fixed as well.... Any tips greatly appreciated!
