Hello all. \n\nI have a C9 that I bought used. I took it out to the range a couple of times, enjoyed firing it and then decided I needed to clean it. \n\nWhen I removed the slide, the firing pin retainer fell out. Cleaned the gun and reassembled it, but I'm worried that I missed a part or that my handgun was missing the part when I bought it. \n\nI only had one spring in the firing pin assembly. It was the thinner, longer spring. The shorter, more stout spring that I saw in videos was not there. \n\nAlso, my firing pin retainer had a smooth ball head, not the dimpled one I was seeing in videos and online parts list. \n\nSo two questions:\n\n1. Will my firearm function with just the one spring or do I need a replacement? (It was functioning fine before, so if it was missing, I didn't notice). \n\n2. Is it possible that I have an older hi point or something like that to explain the differences in parts?\n\nAny advice is welcome. Thanks much.
