So... I recently purchased a SD9VE as a project. I have no experience so I figured I start with this gun. I purchased a Galloway Precision trigger kit, and a Apex spring kit. After watching YouTube I found a video that walked me through the process of changing the parts out. It went fairly smoothly I thought. But now the slide won't come off and the gun won't fire. What do I do? It will cycle bullets through, and when dry firing seems ok, but at the range it will not fire. How do I get the slide off to start over??
