Hey guys,

I apologize if this seems to be a noob question but I've scoured this thread for some time for the answer.

Just got my first hi-capa 4.3 (the FMU dual stainless steel one from WE Tech) and have changed the slide to a Guarder Springfield slide. The internals have been somewhat upgraded too just with the Airsoft Surgeon internal kit (springs, nozzle, piston head). I've also put in all the usual valve upgrades (hi-flos and the valve inside the loading nozzle (forget what it's called))

Anyways, i was test firing the the weapon with the new slide just now and I noticed the slide was being shortstroked somehow. I have no buffers on the guide rod. I filed the some of the notches on the frame to allow for a better smoother cycle. But the slide catch doesn't seem to catch at all when the mag is empty. I lubed all contact points and dryfired the gun, and even on full tank, the slide catch doesn't work.

So i'm wondering, could this be a simple fitting issue (barrel, BBU, slide, anything)? Or is the recoil spring simply too strong (it's 150%)? Even with all the higher airflow valves installed, should this still occur?

Sorry again, if this seems like a noob question.
