I bought this gun and it worked perfectly. Then I read about using a valve stem tool to use instead of the tool that came with the gun in case it got lost. What I failed to do was leave the stem tool in the gun. I didn't realize the tool that came with the gun stayed in it while I cleaned it. When the stem tool was removed, the trigger assembly fell out and somehow a little spring that held the slide stop in place got lost. I did find it, but couldn't figure out how to put it back on the slide stop. Anyway, I left the slide stop in the gun without the spring and took the gun out to fire it (thankfully nothing bad happened). The gun fired, but then jammed, probably because the slide stop wiggled around and stopped the slide. My question: If I take the slide stop out of the gun, will the gun work okay but won't stop the slide on the last round? Everything else on the assembly works perfectly.Help please??
